In Aion 2, there is a premium item that lets you revive during boss fights an unlimited amount of times
I know this game is one of the more pay to win MMOs coming out, but this feature is pretty egregious to the point of being comical.
They are called Resurrection stones, and they can be bought with premium currency. They let you revive during dungeon boss fights as many times as you want, as long as you have a stone.
They have removed the penalty of dying in their game with premium currency. That seems bonkers to me.
I wasn't expecting much from Aion 2 because of the p2w mechanics, but this one seems to be going under the radar.
