Multishot is not used in groups mostly because of the lag that area damage + rockets produce…
Fun enough is that in most cases multishot does better against single targets (unless you use the physical rune in massive density).
In the barb subject… i think they should leave lamentation at 100% (mostly because if they make WW the strongest barb build is there almost no reason to play HOTA or SLAM, because WW is the strongest speedfarm build too), but instead increase hota and slam build damage to be able to do decent DPS in groups, i really want slam build being an efficient thrash killer.
In the other hand, the crusader buff… well… we were talking about it in the crusader forums, and we think that it will not survive, HF is dealing massive damage thanks to the 20k buff, unlike FOH, HF has a complete group of legendaries that makes the numbers go into the broken area…
I would love to see some buffs to some forgotten specs to change a bit the group meta spots, but i think the crusader will set will be nerfed.
