Support build for PVP?
I use it in WvW and PvE, and use a bunker build instead for PvP, but I run http://en.gw2skills.net/editor/?fcAQJAqel0p6d3yyuF17IxIFdO0hUYfDL6R+tsjB-jUCBIOBkUAkWAIPqIasFhFRjVLTQWPLpKbYWcFRrWKAIWDA-w
The utilities are very adaptable, I like the on-demand ranged knockback/blast finisher on the mine and the awesome mobility from rocket boots (Make sure you use it with some form of speed boost, either slick shoes or swiftness).
You are extremely good at stacking retaliation, with multiple blasts available to you. Medkit heals for a lot, and you can use it on allies. EG #5 also forms a similar function. You have AoE condition removal, swiftness/cripple bouncing, and an on-demand permaweakness (Seriously powerful against any kind of power/crit build). If you really really wanted, you could also use traits to give you three stunbreakers, which I think is overkill but really depends on the enemy in question.
You’d want to use Cleric’s or Shaman’s gear most likely, and I’d advocate either Dwayna or Water runes. Keep in mind that on-heal procs happen when you equip medkit, so you can activate them on cooldown without wasting your heal.
