Seriously, OP, your argument is flawed in so many ways. What you are basically saying is, any DPS burst should be able to take out a two man team who is actually working together, how does that make sense? As guard works now, it reduces damage by 5% to the one who is being guarded, and transfers 50 percent of it over to the Tank. Which means, even if you are attacking the healer, you are still doing 95% damage spread between 2 targets.
If a healer is caught alone, can you take him out with a burst 1v1? How about if the tank is caught alone 1v1? Oh wait, you want to be able to go 1v2, kill the healer, then escape out of combat, come back and kill the tank right?
So whats the problem? 5% damage or that you can't take out one person of a two man team in 3 seconds then finish off the other one 6 seconds later all by yourself?
What you and all the other whiners fail to understand is, the game does not revolve around your DPS burst damage class. There are MANY other pvp issues that need to be balanced. And honsetly, you are picking at something that from all intents is working as intended baffles me.
News flash: Healers heal and Tanks take damage, what a novel concept, how does BW come up with this stuff!
