you at least clarify how Rune of Re-Origination would work? Wording on the trinket is not very clear.
Warning: technical mumbo jumbo follows.
At proc time, it checks how much crit, haste, and mastery you have (yes, this is a snapshot, and does NOT include the mastery raid buff). It finds which is the highest of those 3 (tie breaking rule: crit trumps haste trumps mastery), and gives you a buff of +[sum of lowest two stats] to your highest stat, and -[lowest stat A] and -[lowest stat B]. For example, if you have 6000 mastery, 3000 crit, 2000 haste, and the proc goes off, it gives you a buff that provides [+5000 mastery, -3000 crit, -2000 haste]. It does not continue adjusting that buff as stats change during its duration. Yes, this means that if you have a temporary buff to a stat that is not your highest (even with the temporary buff), and that temporary buff falls off during Re-Origination, you *could* end up with negative rating. In this obscure edge case, negative crit does reduce your crit chance, negative mastery does reduce whatever it normally does, and negative haste is ignored.
copied from a blue post on how the trinket works. seems like this is going to be interesting to play with and while my original thought was that it will suck for ww (doubling up on haste isnt going to work and i guess crit could kind of be beneficial if we dont energy starve) it could actually prove beneficial. now this is just plain thinking I havent done any numbers so dont jump down my throat if im wrong.
what if we put mastery as our highest stat to gain the buff doubling our mastery then using tigerseye brew and clicking the trinket proc off. what do you guys think?
