As we more than likely all know that MM goes crit > MS then 48% crit you change to MS weapon enchant etc.
Just curious, 1 Hunter who i raid with seems to have taken the mastery route with MM, i mean im talking 23-24% sniper training buff on damage dealt. Has anyone seemed to feel Mastery can be 'decent' at a point or does it take over MS when MS it at a set % and the fact bosses melt so fast now so dont even need really consider moving anywhere near as much to maintain 90% + uptime on sniper trianing
