This is true, but every healer CAN dispel some, and between the healers, you can get them all. MY POINT IS: If you make the dots not interrupt channeling objectives, then what are the points of these skills to remove them, hell what are the points of the dots themselves. They are meant to be annoying and you want them gone, how about, just remove all dots and the skills that remove them, and give us more straight dps and heals then. Because its stupid. If you got stabbed and were bleeding and its hurt you would find it hard to focus. This is why dots interrupt in the first place. Why make them weaker.
Solve the problem, don't cover it up. Make every healer class be able to remove all dots and give us a better interface to view them, then pvp will be more tactic based, and not just about crushing defenders or attackers and popping doors. All healers do in voidstar will be heal in dps, engage them more, don't make it mindless.
