deciding between ps warr or chrono
I answered this elsewhere, but:
If you have to ask, PS Warrior rather than Chrono. The might requires no particular coordination or timing to benefit from, while the alacrity does. If you don’t know yet, take the easier option.
Also, “with a druid” is approximately-equal to “with a dedicated healer”, and you probably want to go look at what Agony is over in the wiki to figure out the answer to that yourself. It’s certainly going to help, but it’s probably not as essential as people make out.
(Think of it like the “currently OP” class in WoW raiding, which you mentioned coming from. Sure, it might be marginally easier, but generally player skill is going to move your DPS more than the OP class stacking would.)
Druid + 2 viper necro. Power warrior will just die, and condi warrior while good will not give as much damage as 2 necros bouncing epidemic… imo
