Some warlocks are using empowered mana tap pre-pull and then changing the talent to contagion with 1 sec left to pull. 20 sec of 10% overall dmg using a buff from a talent that shouldnt stay if you rerolled your talent. Logs using this exploit should be invalidated.
Add Sindorei Spite(spell prob wront, demo bracers though) same thing. Pre cast doomguard and swap leggos(swap shit as Blood Lust helm thing kinda which I think blizz actually just fixed anyway).
