Just a not on DE...
They are by far the most played race, and I think it's the same on the korean servers...
So maybe you ranked them as top because there are so many of them, and there is bound to be a few good ones there

Just some random rambling hehe
Anyways, I still think NCSoft did a pretty good job with classes... Let's see the results of the last 2 pvp tournament videos I saw that took place on the Korean servers... So we are talking lvl 60+ toons with fubar equip heh.
In both of these videos there was dwarfs in the tournament, that leads me to think that even dwarfs are not utterly bad at pvp, even 1on1 pvp

The last one was won by a Shillen Elder... yes a healer/rooter that the vast majority of players would consider as a crippled child in 1on1 pvp... Still, he won the tournament.
The one before that was won by a Plains Walker, which most people refer as the worse assassin type...
Sure, it all depends on who they fought before the final and so on.... but the point is that each class has it's str and weakness. To be successful you need to know yours and the ones of the class you are facing and use that knowledge to your advantage...
IMO, in pvp, there is absolutely no better class, as long as you know how to play yours and got good equipment (equip being probably the most important thing lol).
just another serie of rambling lol
edit: still I have to admit that SR owns heh... why in hell didn't I play one pfff Hope the C1 nerf is a good change that evens things out
