Q: Build for Solo PVE & PVP (BGs/World)

What spec does best at working well in both PVE and PVP? I'm speaking of casual PVE and PVP.

Which spec will I be able to do well with one gear set, talent spec, and such. I of course have preferences, I'm just a little worried that I'll get attached to a spec that costs me a lot of work in getting different gear sets, having to adapt to two different talent specs, and such. I like getting used to one way of playing and growing attached to it & my gear. I know PVP requires resil, but I also know that resil-less pvp is possible if you're playing glass cannon.

Basically, I'd like to avoid a spec that is suited for players who like collecting two gear sets and such. That's not my cup o tea, but it WOULD be if I had more time. Haha :P
