Guild Wars 2

So as i stated i just hit 80 on my warrior and from 1-80 i have been running signet warrior with GS/LB. I had no trouble at all i hit 80 in about 5 days no biggie. Now that i am 80 I am looking to do dungeons and just run around doing events and maybe some WvWvW. I have been hearing a lot about shout warriors and im not sure if i want to run that because from my research i need to get clerics gear and some healing power. If thats what i need to get so be it. Basically I am looking for some advice on what build/weapon combos i should be running so that i can still do my solo thang(100% map completetion and events) but still be able to be very helpfully in a dungeon environment. I am also debating on just re rolling a new profession because when i picked a warrior when i first started i had the mind set of im just going to do a bunch of damage. Well further research and videos proves to me that is a bad idea seeing how this game is all about working together. I am more of a supportive player so for me i have no idea why i picked a warrior but i was having tons of fun just being a monster with a GS. I have a decent amount of gold saved up from leveling so i was just going to buy a full exotic set off the TP(yes i have enough to buy the gear i checked prices) but i am unsure which route to go gear wise. Any help would be awesome. Thanks.
