I been leeching for a long time since I couldn't find something decent to share. Well here is my find.
As I was doing the Intercepting the Mana cells daily a few mins ago I got ganked by a Nelf rogue while we were both under the effect of the phase buff. Needless to say he used vanish while He was down at 15% hp but here is what got my attention. I was still able to see him even though he had vanish. Not sure why I was still able to see him from a distance but I put him out of his misery. Not sure if this is working as intended or a bug/exploit but I will try confirm it once I find another rogue. Yeah I know...ss or It didn't happen >.>
