Test

I've been playing on and off for over a decade now but I can't seem to get any "good" at the game.

I have one of each profession and almost all are level 80 by now and I have few goals left so to speak. I wan't to play more PvP and WvW for example but I can't seem to get better at it. I always get my ass handed to me by some semi-god.

So I guess my question is, what should I focus on to get better at the game and to be able to hold my own in PvP and WvW? Tips, videos, guides...
