While I wouldn't say WHM is bad, I disagree that's it's fine where it is. There's plenty of room for improvement.

Like, say, how about more weave opportunities so you don't have to keep dia and lucid perfectly aligned or you'll clip (and realistically, you're going to clip anyways because there's other oGCDs).

How about not having PoM have a CD that aligns with nothing?

How about more movement options, so you're not stuck with refreshing your dot (which then no longer aligns with Lucid)?

Again, not saying WHM is terrible, but it's a far, far cry from perfect. As someone that also plays tanks and DPS sometimes - WHM is by far the kludgiest job I play. DPS jobs' abilities (and caster weave windows), and tank abilities, etc all come together sooooo much more smoothly. It's like driving a modern sports car vs a 1960s winnebago with one wheel about to fall off.

I sincerely hope that, some day, healers get the same level of attention towards allowing smooth gameplay that other roles get.
