You can solve TP not updating dots just by mouseovering the targets. But otherwise I haven't yet noticed an issue with this setup. If a target isn't on boss frames or it's name plate isn't showing, it's not important enough. Also after so many years of moonkinning, I can pretty much tell when to dot again without even looking at the dots. You can anyways choose to either re-dot or just switch eclipse for higher NG uptime etc and it's pretty much +-0 still.
Anyways, back to UI. My philosophy is that don't change something that doesn't need it. I have yet to encounter a situation where this hasn't been a good enough solution and I don't really fancy forteXorcist for some reason. Maybe the looks of TP is something that will make me change things, but I'll look into that later.
