Depends on the amount of bad dps in the group.

No really, it is. no amount of good strategy stands up to DPS that can pump no more than 250 dps. What SE did was make ST a faceroll in terms of mechanics - and even then, EVEN AT CURRENT GEAR LEVEL - AT LEAST i100 on tertiary alts - there is that rare occasion of wipes. WoD reintroduced a slightly higher difficulty, SLIGHT, like a smudge worth of difficulty, and people suddenly can't just smash buttons to play properly. I guess people really expect to just AFK and get carried in 28-man fights because it was permissible on ST.
