Guild Wars 2

I just hit 80 as a ranger. I love to WvW, and sometimes do Dungeons.
Can someone help weigh out the options (pros/cons) of the following?

Power/Crit style.
Healing/Toughness (bunker build, melee)
Condition

Trying to figure out what the best route is for my first exotic set.

Depends on your play style. What weapons are you using?

I mean, atm i use GS/Longbow. But ive also used axe/warhorn, sword/torch, sword/warhorn.. :p
Im pretty leniant on which weapons i use, or the build. I guess im looking for
“If you go with X style (condition, for example) youll excel vs XXXX and at roaming/dungeons/zerging etc… HOWEVER youll get crushed by XXXX/Wont fair so well doing this” kind of thing?
I rushed 80 in a week upon reinstalling lol
