"Vamps have no ranged attackes either, just a 10sec timered power tap."
Lol learn to play your class, VE spec Vampiirs have a ranged damage spell, the Vampiir's Heat line (Starts at level 1)
Also. Vampiirs are leather wearers, and will go down easy to anyone carrying a Heat Legendary.
Any stealther (Hib or Alb, I dunno about an SB) that gets the jump on one of them will easily kill them. PA, CD (Stunned). If they don't purge, melee them down with Heat Legendaries. If they do purge, wait for an evade and Dragonfang or Diamondback them (Stunned again haha)
If you have it, use Power Leak (Master Level style) and they become useless.
Lastly, Skilth: You are still in the BGs. Vamps are WAY overpowered in the BGs. Once you get up into NF and get fully ToA'd out and buffbotted, Vampiirs will be RP fodder for you.
