Ok, I'm going to go in here and it isn't going to be pretty. Buckle up.
Your mentality is a huge part of why healers are in this exact hole they are in. Neir AoEs are infrequent enough that a WHM can easily top people before the next AoE with Assize, Lilies and Asylum.
But no. You demand that they heal you back to full
immediately after the AoE because otherwise your comfort blanket might get a bit ruffled. Oh noes
The only reason you even suggest the Lily system might need a nerf is because you are butthurt that a healer prioritised their overall contribution over your feels. Get over yourself. By your very own logic, nerfing the Lily system would make things even worse. But that doesn't matter since you've got to put that healer back in their place and that's what counts right?
Your attitude and mentality disgusts me.
