Seriously, what the heck?

[protagonist]

I'm seeing people like WaterLord practically WARP across the screen and casting about 5 bullets a second, and I'm on a fairly fast computer with broadband.

Correct me if I'm wrong, but isn't that quite unusual? I've seen people with higher levels that don't go that fast, so what's up with this. If this is actually possible to begin with, there really needs to be a cap on speed. I cast a spell at someone, he runs all the way around that person in time to block the spell. That's kind of odd. Either the speed of people should decrease or spells should move faster.
