Nexon is experimenting

By "pay attention to avoid" I don't mean crap like the Balrog boss has with his reflect, Nexon. The boss actually doing something noticeable before casting the skill, not blinking 1 frame faster or something.

That's what I saw with Astroroth, he creates a purple/black whirlwind around him, the animation takes about three seconds, that's more than enough time to get the hell away from him. Then a reaper appears above him and creates an explosion which starts out small and rapidly expands before vanishing. The only problem implementing something like that would kill you in one hit would be if you're trapped in a corner, no place to run, you're pretty much screwed. However, it can be like Land of the Wild Boars, with teleporters on the sides, to avoid that minor inconvenience.

Like others have said, this game still has a lot of potential, it's just a matter of implementing it and having it work right.
