I have Guild Wars "Porphecies" and I play an "Elementalist" and a "Warrior" secondary so I was wondering if there were any good "builds" to PvP. I want to get into "Guild vs Guild" and "Heros Assent"
You'll need to buy the other expansions "Factions", "Nightfall", and "Eye of the North" in order to have the skills unlocked for meta "builds" that are required in pvp.
with just prophecies there is only a select few builds that are accepted by groups that you could use such as shock axe or dev hammer. other than that if you want to get serious about pvp you will need to buy the other campaigns/expansion have a bigger selection of skills to use.
