Researching this question a bit better, asking friends and stuff, I realized that this answer has a problem, lvl 500-, especially ed 500- can't take enough of the skill wheel, since most of your setup is aimed at helping your team and friends by evenly distributing the few sources of damage that this skill wheel provides for them.
That said, I still have an answer I'm developing, but I'm probably only going to answer half of it here, explaining why the ed skill wheel is so limited for lowbies, then adding another question talking about how each axis impacts the ed game (right now I can separate it this way: bottom left: offensive, bottom right: utility, top right: support, top left: defensive) either way all the ed axes help with your healing, but with different approaches, however, I don't think this is the question to answer all that.
