Set_R Most of us have lived the process for far too long to care about the process, it's just a nuissance. It's like defending the idea of not rushing to end game, when you already played through it 100x.
I personally hated this mechanic, because the only way I knew it existed, was from a modded grf that told me not to attack the mob. Same goes for earthquake. No cast, just death approaching. That's a gravity interactive mechanic for people to buy cash shop gear, or tokens to revive. It holds no real strategy, it's just meant to instantly kill you, and very suddenly.
I would like to see a cast on this skill, but a visible one, not some 80% variable cast. I want to prepare for it, not be blindsided by it, because it is a very stupid mechanic, and as someone mentioned: "Just one shot to avoid it xd"
