drain life has no MR check??

Always using something is not the definition of overpowered by a long shot.

if i have water magic, i always use quickness. But not many suggest thats overpowered. If i have astral, i always use astral shield. If i have blood magic i always use devils.

Always using something doesnt make it overpowered, it just makes it one of the benchmark spells for that path (and yes, death has many of those). If anything makes lifedrain overpowered, its just the fact that it cannot be resisted.
