I havent really had much to say about the dot nerfs but I figured I would talk about it finally.
Single target dots and aoe dots should do the same damage and cost the same amount. Why is this ok when one only hits a single target versus the other hitting many targets? Aoe dots have a giant drawback to them, for the most part they are all stationary place abilities. There are exceptions but most of them are stationary placed abilities. Caltrops, endless hail, ele wall, liquid lightning, twisting path, winters revenge, all only effect things in there effect radius. That is a big drawback in this game, especially in newer content where the bosses move so frequently. You both lose out on uptime and have to cast aoe dots more frequently compared to single target dot which stay on target when the bosses move.
Personally I think that is enough of a drawback to justify aoes added bonus of hitting multiple targets.
