afaik raid sims are meaningless to us as multistrike can proc twice in pve and only once in pvp which really shits on its effectiveness. it also looks likely that we will be spending most of the season getting trained by rogues or double melee (or both) and multistrike doesnt seem like an attractive option there... maybe could work as shadowplay though?
right now most people are going crit mastery. stats like these are generally strong that the start of an xpac as haste scaling sucks at low values and crit lends itself to how early seasons play out HOWEVER im not sure about crit as it did get nerfed. that said, with multistrike being garb in pvp and haste seeming to scale poorly I feel like its the only option.
arena has been getting the bandaid approach for fixes for several years now and i cant see it changing
crazy watching their major tournament revolve around and be decided by a shitty bandaid fix to poor balancing
they will probably make dapening start when gates open for everyone then make it stack twice as fast and have the crowd chose you pop up at 3 minutes because they could give less of a fuck about balance and are happy as long as its possible for games to end
