The update to Poison/HP Burn explosion skills has vastly nerfed damage when it said it wouldn't. 

My team used to clear the level 20 Spider (before the boss gets the passive reducing damage based on MAX HP damage skills) dungeon in 5 turns, 15 seconds, highlighted by Elenaril's poison explosion, but her attack is doing a fraction of the damage now. I tested it what Zavia just to make sure, and the same thing is happening. The damage went from about 60% of the bosses HP to like 70,000.

Why is the damage severely nerfed when the update said it wouldn't? 

Poison explosion skills are already limited in their usefulness due to many bosses having the passive reduce damage from MAX HP based attacks, and now it can't even be used against bosses without this passive thanks to the nerf?

What the hell happened?

Incredibly annoyed
