Guild Wars 2

I just got my warrior to lv 80 and i want to gear him up with all the dungeon tokens i have accumulated. My Guardian is full P/V/T exotics and that seems to be a pretty good setup for blanket-effectiveness in this game’s combat system. Given the fact that you can’t really specialize into a role (healling is ineffective, indirect, etc), what is the best option for me to gear up my warrior in a way where all or most weapon / trait setups would be effective? I don’t want to have multiple armor sets because that gets expensive and frankly, i don’t really think there’s that big of a margin of difference between what P/V/T set can do as opposed to Power/ Precision / Crit damage, so on and so forth. I may be wrong, but this game’s character attribute-number system is very vague and confusing.

Any guidance is appreciated!
