Heck unless you use a story skip pot the stack circle shows up a few times during HW. Xephletol, Final steps of faith are two that I can think of. There are a lot of mechanics you see done more than once by the time you get to the end of 4.3 unless you story skipped. Anyway the whole I want to use all of my kit thing isn't going to work because at least for ARR dungeons trash dies too fast and is spread out enough that your procs will have timed out. The only place you'd even get a chance to see a good part of it is during boss fights. HW you might get to see a good chunk of it on trash and get more during bosses but again the spacing of trash in a lot of dungeons in HW isn't great. So unless your group speed runs and pulls everything up to a boss I can't see what you want happening. Also speed runs for a lot of new people isn't good just due to them not knowing what's going on or what to do. It also relies heavily on the tank and healer to be on point and know how to use their kit.
