Best Tank Build?

Take a quick read through this thread:

http://pwi-forum.perfectworld.com/showthread.php?t=906402

There be some good advice there...

As for weapons... dual axe/hammer or poleaxe/hammer be about the extent of your choices. However, trust Fuzzy and be sure that you are working on your crafting skills as you level. Of the 4 weapon types, you should be able to blacksmith any that will suit your needs on your way to bigger and better things. Many players Fuzzy sees neglect their crafting skills and regret it when they reach the higher levels. It needs to be a constant process that will grow your crafting ability along with your character.

For skills... there are many posts about what the priority should be, just browse around our sub-forum. There is much any barb can learn if they take the time to read a bit about our class here. After all, isn't that the main reason for the forum? Also, there seems to be a few different schools of thought on specific skills. (Fuzzy referring to how fast to improve true form and alacrity level) Me would say a concentration on flesh ream, devour, alacrity, as well as BKI buff and any of your passive skills you are able to improve won't steer you in the wrong direction.

Just keep reading what you can here and growing your character in-game. It always makes Fuzzy happy to see new barbs reaching out for advice. There are many excellent and knowledgeable barbs who post here. The new and aspiring barb's who take the time to ask and read are the ones who do our class proud and never have trouble finding a squad or tanking a boss or pushing their character to the limit.

I'm currently a level 36 barb (still kind of new to the game) and i was wondering what skills i should try to level first. I've read other threads on skills, but those mainly only focus on strictly tiger or strictly humanoid skills, never a mix. I'm trying to go for a tanking build, but i can never really find any parties for quests, so should i just skip the humanoid skills (other than buffs) and just get tiger skills, do humanoid skills for these levels and get tigers later, or mix? If anyone could help me out that would be great.

Personally, I go with tiger form skills only. Sometimes I regret this, especially when I end up being a party DD when another barb is party tank. Usually i just stay in tiger form and support with Devour and Alacrity.
Tiger skills = tank skills. Humanoid skills = DD.
Flesh Ream - most important
Level Alacrity of the Beast, all your passives and buffs too.
I love Sunder, it is so much fun when fighting 3 or more mobs at the same time! It does eat 2 Sparks though. It makes mobs bleed and you regenerate.
Endgame dex = around 60. I have mine at 50 natural now, can get to mid-80's because I been hoarding +dex gear. I use claw/fist when I'm bored with tiger form or sometimes when helping a lower level with something. I'm doing something fancy-schmancy that isn't typical. Fluffy and Steelstar both gave good stat builds. You need 3str every level to use the current heavy armor and hammer/axe weapons. Most barbs just stat enough dex for gear and put everything else into vit.
So, yeah, tiger form is best for being a good tank.
I like using only polehammers / poleaxes. The slightly higher attack rate really doesn't make a big difference, except in my head. Go with whatever current lvl legendary hammer/axe weapon you can afford. I'd rather hit more often, as in attack speed and not missing, than hit for more damage. After all, I'm a tank, not a bloody BM or DD.
Standard builds have your dex rising more slowly, so it's sometimes smart to shard your weapons for accuracy instead of extra damage. I raised my dex prematurely so I could have claw/fist fun. And the Blood Bath skill increases your accuracy at the cost of some hp anyways. I didn't think it was that useful but I'm changing my mind about that.
Wear heavy armor! I usually shard my armor for physical protection (garnets) but most barbs go for +hp. I'd rather be a rock than a meatbag that can take lots of beating.
You do have to be in human form to use most your buffs (Strength of Titans (+str party buff), Beast King's Inspiration (the +hp party buff), Blood Bath (the +accuracy skill), but Poison Fang requires tiger form.
You can use Bestial Rage in either form but you have to remember to attack again after casting it or you just stand there looking cute. It's important because Bestial Rage builds your Chi up faster. As a tank, your job is to keep the aggro so clerics and squishies don't die. Flesh Ream (FR) is your most important aggro skill and it takes Chi.
When partying with powerful DDs, you sometimes have to spam FR all day to keep the aggro.
Roar also grabs aggro from an area, so you can get the attention of all the mobs in an area instead of having to FR (Flesh Ream) each one individually. Roar won't hold aggro forever so keep an eye on the mobs.
I've never been 79+ so I don't know about Untamed Wrath, but it's apparently an aggro grabbing area skill too.
Alacrity is real important because it cancels spell channeling of the target. Some bosses have nasty aoe spells and your reflexes and ability to get Alacrity off in time can save the day. It's so much easier to fight Zimo when he can't even get a spell off. I haven't been endgame, yet, but I'm willing to bet the bosses nasty spells only get worse - making Alacrity even more important.
With caster mobs I rush up and FR them, they run then turn and cast, I use Alacrity. They run again unless Alacrity freezes them. I catch up and FR again. Another 4-5 hits and they're out. Heavy armor is weak against magic so make Alacrity your friend.
An hp charm is always nice to have but that depends on personal finance. I was soloing the 49 culti bosses in my mid 50's by feeding them my charms. It's really always nice to be friends with a decent cleric. Or 2 or 5.

On my genie, I have Solid Shield (a must for Barbs), Wind Shield (extra attack speed + protection), Second Wind (fast heal) and I'm considering Tree of Protection (TOP).
Another thread in the barb forum discusses apoth items that can help barbs. I don't use any but it's something to consider.
I've been using Apoth charms and Life Powder on my Sin alt and these could be really useful in tanking.
