To be fair, while I agree that the DPS kits for all healers are really bad, I have to agree with the "troll" here. I don't think DoTs are an interesting mechanic for healers currently and even in the past...
There is no proc tied to them, no gauge tied to them, no other abilities tied to them...just a debuff icon on the boss that basically does nothing. The only good thing about it is that every few GCD you get the opportunity to press a different button, which could be achieved by a non-DoT GCD too...
