Guild Wars 2

A similar thing happens to me about 70% of the time. Any character with available stealth (mesmer/thief) are litteraly invisible to me for great portions of a fight (talking 10-15seconds). Just 20 minutes ago my team and I was fighting what seemed to be 3 players on my screen, yet I took dmg from unknown sources. While kiting around for bout 10s, suddenly a mesmer and his 3 clones appear, plus a thief. But the thief seems to be phasing in and out of stealth at completely random intervalls(this by walking normaly, not even attacking) , the mesmer not as much. Now I have played thief alot myself and I am familiar with their stealth skills, and this is not just thiefs with impeccable stealth-skill timing, everyone and anyone does this, be it pistol, sword, or shortbow thiefs. This might be rendering problems, but I have no idea wether the problem is on my end or on the client’s. Could also be lag I guess, but I doubt 70% all thiefs have 64k modems. This is a huge issue to me, and makes the game really unenjoyable. Im playing spvp btw.
