Guild Wars 2

i just hit 80 for the first time on my ranger i still dont know too much about the game.im wondering on how to go about getting better gear and pvp/pve builds.should i start doing instances?if so which ones should i start off doing.

I think this game needs more healing classes.i mean like real healing,you cant really expect for this game to progress in a pve standpoint without having more healing classes and healing abilities.from what i have seen you can pretty much expect to die on bossfights run back to the waypoint and keep fighting.i would like to see more skill involved in PVE if not i think that ppl will get bored and possibly quit the game.thats just how i feel about the situation.
