The Problem with Healer Feedback, and requested changes

[Rilifane]

Also why are all the DOTs 30s, making them have different durations to the other healers would help a lot, like if SGE's was 18s so we're pressing eukrasia more often maybe it'd feel at least slightly more interesting

That's something that SE seems stubborn on for some reason. Give us buttons but make us press these buttons only once every 30s or less.
It's not even about the amount of buttons but how often we press them and under which circumstances. A skill could be incredibly well designed and interesting but if you slap a 3min cooldown on it, it is still something you only use once every 3min tops.
Just with shorter dot duration our rotation would look different. Nevermind things like dots with different durations, lower cooldown on some skills or incorporating already existing skills like Toxikon into our regular rotation as well. The less impact a single button has, the less punishing it is to mess up the timing.
