Lol it's always after I don't play for a bit and want to come back that I can't log in.

So I have tried to look online for a rotation that would work well. Even the sticky for tanking seems to be a little out of date because wither now adds stacks of HD. Right now my rotation is: Dark Ward (pre-pull) Discharge Wither Shock At this point, if I dont care about force conservation I will Thrash, if I am, I Saber Strike once or twice till Wither is back up. If lots of adds, I will Lacerate here. Wither (this gives me a 3rd stack of HD) Lightning I then just basically keep throwing down those abilities as they come off of CD. I have tanked everything in the game up to BT HM without a single problem with threat. I never use Assassinate either. Is what I am doing going to be a problem in the future? And is Wither giving stacks of HD going to change things? Because I use FL every time I have 3 stacks. It does great dmg and heals considerably.

It is because you are level 19. You only started specializing 9 levels ago. Ive been tank specced since level 20 and it definitely got better when I got Talos. You just dont have enough abilities. To be honest, at level 50, I feel like the best aoe tank in the game. Dunno if thats true, but I am great at it between 3 instant cast aoe abilities. Just remember that discharge hits up to 5 targets near the original target, not you. Don't worry. It gets better...waaaaay better.
