"This is my playstyle" is a poor argument for being bad.

[Eul]

I ran into one of those ice mages before. Cast nothing but blizzard 2. I was the tank and queue with a healer in my fc. The healer told him he should be casting fire spells like fire 2 and flare for aoe pulls. His response, "blizzard 2 is more mp efficient"

Nothing we could say could convince him otherwise. The run was horribly slow. There are people who don't want to hear advice that will help them play better.

Seriously I kinda want to know what they were thinking. Is it like, "This blizzard gives infinite MP so I'll just spam this than using Fire!" or "This AoE blizzard gives infinite MP so I'll just spam this than using Fire!" or "This Blizzard IV gives infinite MP and Enochian buff again so I'll just spam this than using Fire!" ?
