I91 will be fine as long as your accuracy is around the 490s.
Don't hinder your tank to be the extra DPS.
Well I've got about all the Soldiery pieces that're worth owning for now. So while I'm certainly not going to consider buying something for my DRG until our group clears T7, I figure that I should be open to purchasing at least one piece, so long as it doesn't heavily delay acquiring the Tomes I need for my Tank weapon.
More though, I'm thinking along the lines of, 2.1 BiS items, crafted pieces, or whether it's really worth farming the iLvl95 Levi weapon, seeing as I already have the T5 Spear.
My basic rotation seems solid enough, though I really do need to install ACT sometime. However I tend to take too much time to get into optimal positioning and such. I really need to learn how to use that leap move and such, to whittle back my downtime.
Edit: Also, we'll probably try the fight once or twice with everyone going as their main class, just to be certain we aren't already capable of clearing the DPS check. Since a large portion of our group is sporting Animus weapons, it actually is possible. >_>;;
