My proposal is to have a "special" type of PvP arena/battle/etc. that gives you more slots for skills. I thought it would be nice to have the same 8 slots, but get 3 more bars that you could rotate through. Of course it would be nice to have "skill sets" like the weapon sets that are already in the game (I read that one somewhere else) so that you could easily switch between what you wanted before the match started. That would be a cool feature whether or not the new PvP arena was a reality.
Anyways, the way that it would probably be coolest is if you could join PvP battles just like you can now, but with the added option of it being "All Out" PvP.
It would not change anything else about the game. I think for the most part the skill limit is a great Idea. It encourages diversity. And if you think about it you would still be diverse with an "all out" kind of thing. 34 skills of 300+ is still a small amount of what is possible. And you wouldn't get any more attribute points so you couldn't make more skill trees stronger.
Well just a thought. It would probably make more people attracted to the game for one, and give the long timers something else to switch it up with. And the implimentation of such a thing would be almost painless
