Return of Reckoning

Tactics wise what do you run for single target?

Also in the sent jewel would you recommend running +4% crit, or the +spell power tali? Have to admit I'm not completely sure about the value of intelligence vs spell power.

I'm currently running Offensive Sov cloak, gloves, and trinket, bloodlord chest and shoulders, sent helm and jewel, with (I think, might be vanquisher) invader boots and belt while saving up for the offensive Sov chest and shoulders.

I'd adventure to say buying order while approaching RR75+ for single target is cloak first, then trinket, as you can replace genesis in those two slots, then gloves, chest, and shoulders. Chest and shoulders is up to personal choice as I don't see losing the bloodlord +Wounds 2 piece bonus worth equpping 4 piece offensive Sov, but could be nice for keep sniping.

Any advice on which pieces to go after next as I start building my AoE set?

While its fun to blow stuff up, I find that I kill more as defensive spec, when solo or small man without a guard.

if you are using a tactic that makes crits 50% stronger then its usually best to stack crit as high as possible. you should easily get 1050 int if you have int tactic, otherwise use 2 gear sets to get double bonuses.
