Good news for WWs.
So in the latest interview with the game director, he acknowledged that SEF is broken and that they are trying to fix the bug, if they can not then they will be just straight up buffing the damage of SEF to compensate for it in 7.1.5.
Edit: He also touched on the Serenity "bug fix" that is having it revert the CDs of abilities back when it expires. Said they are looking into it and may revert it back or just buff Serenity's damage to compensate.
Odd how they left the shittiest talent of that tier, Chi Orbit, out of the conversation. That talent needs the most fixing. That talent is so bad, people are just pretending it doesn't exist now.
