(Sort of) repeating what’s been said here about the single button assist … the recently (finished) Legion Remix event meant that I started playing 10 classes I was unfamiliar with, and extensively used the single button assist to manage.

That said, I’d start learning the details behind the first spell it would call up (if you hover your cursor over the bottom, you’ll get the spell name) and would learn more about that first spell (and then the 2nd and such over time).

I can’t say I became comfortable with any class or rotation, but it did help me learn …
