If the additional stat points are wasted, it feels pretty stupid that it is so easy to go over the 100% "cap". Maybe there was a chance of an extra proc or something like that when you went higher than 100% ...
Many shamans are in this dilemma now (without going for mastery at all, my shaman is at 110% already - not fully geared yet)
Yea, maybe it is indeed best to just put the haste enchant on and not worry about it anymore, It just feels a little sad when "Elemental Overload" looks so tasty.
(20% increased chance to multistrike - 20% extra damage from multistikes - gain 10% more of the multistrike stat from all sources)
BTW: is versatility below multistrike and crit still?
