It IS goign to end up a dead spec, with destro most likely being the go-to as there are plenty of cleave / high prio adds fights in ToS and while Demo is simming higher atm (like stupidly higher) Demo also has the movement tax...
Probably as the last sims i saw had destro ST something like 60% behind Demo, tho demo just got a big hit literarly today....
Hardly all fights but Destro was viable on both Elisande and Gul'dan , Elisande seeing a majority of Destro logs and Gul'dan about 50% aff 25% destro 25% demo
Sure it's sucks, it was powerfull with the t20 set bonus, but dw it's gona get buffed back to 2 after tomb right......................... right?!.... guys?! *wrists*
Ye atm looks like aff is playing like it did in 7.0, great with adds but utter trash in cleave and ST (i know it's simming above destro and under demo ST atm but destro is their new baby so mark my words it WILL get buffed during HC / before M comes out) and Demo took a hit soooo at least there's destro to look forward to?
(also look at mages, fire wasn't brought back up and frost got castrated and people not even looking at arcane for near a year now... gotta keep that hamster running so i'd wager my 1 remaining nut Aff will not be ALLOWED to be good in ToS - and it's not tin foil at this theory, cockups are one thing but blizzard has been nothing short of malicious this xpac with heavy handed changes)
PS also Combat for rogue got killed off pretty quickly and now Ass is getting the same old treatment as well, if the AP / leggo system stick around for the next xpac i will never play a pure dps again as at this point they are literarly rotating specs, the grind must flow!
