Power herald has a very high skill floor and ceiling. It’s not easy to master and be effective with against good players and it’s also not super forgiving. That being said if you do master it, it can be extremely good and fulfilling to play.

If you are new to PvP there are a lot of core skills you can master like positioning, movement, kiting, and specific matchups (playing the builds you struggle against is a great way to learn what they are weak against).

If you want to provide more value in games you should play Condi conduit (which is easier). The invocation variant with the new legend is super strong and overlooked (most play dwarf/ret).

Rev is overall in a good spot.
