Level as mist weaver until level 24 (when you get the chi cost reduction on bok down to 1 chi). Between 10 and 24 MW is faster due to teachings of the monastery, no cost bok and RSK resets. Even with multiple mobs MW is faster as a fully charged Bok will one-shot most mobs at this level range, so unless FoF kills them all in one channel, you make up the speed due to your single target kill speed.
After this WW is better as Bok becomes spammable. It only gets faster as you level tbh. I’ve never found monk particularly slow to level and I’ve raised a few. At max level I pretty much insta delete most non elites and haven’t found an elite I can’t solo without breaking a sweat at all. The only things I can’t so far are boss mobs in naz, but I’ve soloed the world bosses for WQs in other bfa zones.
Now in dungeons and raids? Different story. Let’s just say when we get close to our ceiling it doesn’t shift very easily and sits a bit lower than others, who continue to scale quite well. We’re not pants, but the competition does show us up outside of burst windows.
