I got the MH from the campaign task for my one alt that had progressed the campaign enough to do it. It gave me a choice between the L70 weapon and the box of random L60 weapon, just like the task description said it would, and now the weapon's sitting in my alt's inventory waiting for her to reach 70.
I'm a bit better off than the OP - my main is a GWF, which means in PVE I am like unto a god. Or at least I was, before mod 6 hit and I had to replace all my gear. Now I'm in mostly L70 blues and I can still solo DR lairs without too much trouble, but Sharandar lair bosses are a rough fight and regular IWD mobs can kill…
Alternatively, if you completed enough of the mod 4/5 campaign to be able to make a dragon artifact weapon, you can do the same task again to get the Elemental Fire artifact weapon. I did this myself on an alt, because there's no possible way I'm doing Spinward Rise or any of the other EE zones a second time.
I really hate this mod. After forcing myself to finish the new questline on my main, there is no possible way I'm doing it again on any of my 4 alts. They can level to 70 off invocation and leadership XP. My other objection is gear, specifically how to acquire decent L70 gear when I don't like doing hardcore dungeons.…
Behold the male GF (helm, torso, and boots included - gloves will have to wait until tomorrow). I'm really not liking that helmet design. Something about that weird little feather-like thing on top just doesn't seem right. Next, the male HR (similarly without gloves until tomorrow). Again, the headpiece seems off to me.…
