I know when I first started playing I thought I was lagging when I wasn't. I thought I was casting when I wasn't. It boiled down to how the game handles cast times. I'd be thinking to myself - my cast bar is halfway done and the previous fire ball just hit...that's weird. Or the - I can't cast until my fireball hits idea from other games and this one being different.

Let's just say I was fubar my first 20 levels figuring out casting, the bar, the animations, and when I can cast again. It does feel slow to me, but I played DCUO a very long time...so that might be why. I also had to move my cast bar from its original spot to the bottom right center so I could actually see it when I was playing. It blends into the game extremely easy.
