How not to be a mentor

[Rikizza]

No it’s just we are at the point of healer CD’s (especially on SCH/SGE) where the tanks performance is functionally irreverent to your own healing plan because the tank can be a paper thin zero mitigator and it shouldn’t matter because you have so many CD’s to mitigate this problem

If your tank is good you are irrelevant, if your tank is bad it doesn’t matter because you have so many CD’s to mitigate it. In high level content if you are relying on the tank to be decent to not completely come apart at the seams you are doing something wrong

I must be doing something wrong then. This made no sense to me. What does healer cooldown have to do with anything? Confusion.
Also Isnt this to over complicate things? Heal when they have little hp,(which is alot if you are with tanks who dont use defensive abillities and when people dont know mechs) dps when everyones good. No?
