In about a week many of us will probably turn to using AT's more frequently than we did in the past. So it's probably a good time to discuss which AT's may be up to snuff when it comes to end game. I am by no means an expert. But I have played almost all the AT's in the game and do have a special love for them.
Most of the below are my based on my personal opinions. I'm hoping others will chime in with their expertise.
My Personal Favorite ATs
IMHO comprable to a well-built FF in just about every way. Nice damage, sturdy, and can apply a lot of debuffs. It's possible to tank with this with sufficient support. But also works as a melee DPS.
I still see players getting top leader-board spots with this AT (Dragon's Wrath). One of my favorite AT's for general PVE.
Tanky, Great DPS, and versatile. Players solo elite lairs with this AT. I haven't pulled that off yet, mostly because I'm lazy!
Sturdy & Versatile healer. Lifedrain + AOED makes this a nice AT for events and Cosmics. Energy management can be tricky.
Sturdy healer with good debuffs & crowd control. I've taken the Witch on Cosmic runs and events. Life Essence is an excellent heal. Plus the Witch can rez herself and others.
Any of the Ranged DPS AT's.
Ranged DPS AT's are in pretty good shape after the various revamps. With my favorites being the Icicle and the Telekinetic. I've seen people score top leader-board spots with DPS AT's.
As I stated previously, these are just my own biased opinions. There's a lot of knowledge out there about AT's and gearing them, that doesn't get shared. Mostly because in the past the game was very focused on Free-form. I have a feeling that's going to change, and significant number of players are going to rely on AT's more. So if anyone reading this wants to chime in please do. The community really needs good information about ATs (other than the tiring opinion that AT suck).
