Some stuff is blanket, some clearly specific, but as itemized as possible:
Destro:
*RoF damage now works like the kalecgos (blue aspect) buff on the madness encounter IE it explodes to everything in its radius when it deals damage. Bring ember generation back but its now clearly good for aoe, less so for single target.
*Mannoroth now works with F&B
*Conflag on a 10 sec cooldown, backlash back (pvp)
*Charred Remains gets a damage buff of 8-10% flat its just too weak and balancing around 4/4 T20 isn't okay this early.
*Fel Flame back (you get what...5x off before oom anyhow? mana forces sparing use...
*Change ember generation to have a higher base/hit and lower crit generation value and slightly bump generation.
Affliction:
*soulswap now has 2x charges on 12 second cooldown
*Nightfall unlucky streak protection tightened up
significantly, RNG generation slightly - should have enough shards to keep it up without worry. Procs should make you feel powerful not mandatory to keep the buff up. Target nightfall restriction at 2 if not 3x targets. 2 or 3 target nightfall sure.
*SB:Haunt is now a 30 second buff with haunt as instant cast. Nah.
*SoC has a .5 faster cast time, detonates on impact, and needs a buff. Maybe.
*SoC minor glyph: your SoC is now instant but detonates when you haunt it or expiration (think lock shrooms but needing targets). Sounds really cool.
Demo:
*haste % increases ToC damage similarly to crit scaling on soulfire. Why in the world should haste increase the damage of an ability? What about shorter gcd?
*pets take FAR less damage in pvp (like 50% less) or maybe 20%?
*Imp swarm glyph now baseline, 2 min CD, launches 5 imps. Dunno, could be too good maybe, too flexible.
*Hellfire damage buff, can also channel it on a distant target. Sure.
Mana:
*Destro: get mana refund on soulburn back I mean c'mon. Destro doesnt have soulburn anymore.
*Demo: Lifetap: grants 350 DF 90 sec CD, baseline mana regen far higher. Whats wrong with old life tap?
*Aff: lifetap grants 1 shard, 60 sec CD, baseline mana regen far higher. Nah, haste will fix it.
General:
*Health funnel given back to destro c'mon. Have all of my yes.
*KJC needs to last longer or have a shorter CD or make unique. Its a copy paste of shamans SWG.
*Dserv pet attacks grant equivalent amounts of emberbits or mirror nightfall tick chance. Would be too good i believe.
*Drainlife no longer shadow school, call it nature or fire OR make it uninterruptable (pvp), castable while shadow is locked. Dunno, should be an different school for affli maybe.
