I'd hate to say it, but...
These effects are making the game trivial. When everything either runs away from you or is paralyzed, there isn't much to do but stand there and watch.
They aren't so uncommon that you won't find yourself in a group where every melee has one or the other (or both). And then it gets pretty absurd.
When anything that hits you run away and anything you hit is paralyzed, well...
I understand this doesn't completely remove the need for other classes with different roles, but let me say it sure goes a long way, and that worries me.
