Whats about facing higher level enemys? I always found that annoying...
At your level, high level enemies are problematic. In fact, at every level, higher level enemies are difficult, for rogues.
We prey on the weak or ill-prepared.
Evasion, well timed potions, and later a blind, bandage, Gouge, Kidney Shot and much later combat readiness helps, but we aren't meant to face out opponents on equal footing. Suprise and exploitation are our strong suits. It is not for everyone, skill-wise or stylistically.
Assuming that you are a new player, you will learn more about the game, faster and more comprehensively playing a rogue than any other class.
Well, at least, that is in my experience. The only other parts you really don't learn are healer mechanics (which really are quite variable) and tanking tactics (which you really need to roll a tank to learn) for pve. But in PvP, there is nothing like the crucible that is rogue pvp for learning other classes because we have at least a limited counter to nearly every class in the game, we can optimize our tactics to suit the situation.
The optimal solution is nearly never, "just beat the crap out of it".
