I currently have a Gnome Subtlety Rogue lvl 55. I am building her specifically for PVP. Currently my biggest problem is trying to kill healers 1v1. These can be priests or warlocks or paladins, with ambush I'm able to knock them down to about 1/10 health, but before I normally can finish them off they're able to do a full heal, and of course then going 1v1 against them I normally lose as they keep healing and I'm unable too.
Lvl right now is 55 but I'm going till 85, but do enjoy doing pvp along the way.
Are there any specific tactics for dealing with healers?
Assuming I'm 1v1 against a random healer in a battleground, and no one else interferes.
