Looking for help regarding PvE & WvW
http://metabattle.com/ is probably the go-to resource for the “recommended” builds for WvW. There are a range of those, so just go browse and choose what you prefer.
For ascended gear, it’s more or less a wash — you can use the fractal or PvP paths, but they require crafting, and are only about 20 percent less expensive than the “normal” crafting path IF you buy all the materials for each approach.
If you have some already, it depends, but I’d suggest http://gw2efficiency.com/ for that — their calculators for crafting will help you figure out the “best” way to get the gear.
If you’re looking to roam in wvw, metabattle probably won’t help you in most cases. I’ve been seeing just about every class roaming now and not just mesmers and thieves like just before HoT. In my experience with reaper, I never had mobility problems or issues with gaining distance despite complaints from the rest of the forums. The only thing I actually wouldn’t recommend is ele since I have personally not seen an effective one for a long long time.
Other than that, pick any class and just practice it.
