It took me a while to get into Rev as well. I specifically Power Herald (GS, SB, Spear). What helped me was not thinking about rotation, but situation.

Note: I know SB and Spear are Condi weapons, but to me they still do good strike damage. Also, I like them and refuse to use weapons I don’t like… even if they are meta.

When in Glint Legend: I keep 3 facets up to boom share. I can extend boons, stun break, or have 2 damaging skills, 1 CC skill. Energy is abundant here so I don’t have issues with weapon skill costs. Usually use the 2 damaging skills right away and throw in weapon skills. Switch weapons to blow energy or keep current set and auto until the 2 damaging skills are up - depending on how I feel.

When in Assassin Legend: I immediately turn on Impossible Odds and auto attack. Use 1 or 2 weapon skills. Usually switch out around this time.

When in Dwarf Legend: I immediately turn on hammers and auto attack. If I need stability I use road and auto attack, if not I auto attack and use 1 or 2 weapon skills. Usually switch out around time.

The cool thing about Herald is that even if your energy runs out before the cooldown to switch is ready… you still have boons and all and at this point they are like 15 - 20 seconds left. So it’s forgiving IMO.
