The rogue is more like 4th or 5th place.
1st place.
Crossbow expert+sharpshooter
2nd place
heavy weapon master+polearm master
3rd place. Sharpshooter+ bow
4th place Great weapon fighter+ half orc champion
Sorlock is 1-3 depending so the Rogue falls even further down. I also need ot have a look at lance+ great weapon fighting+mounted as the advanatge offsets the -5 to hit and you have a shield and a d12 weapon in one hand. Throw in some ranger and paladin builds and I suspect the Rogue will fall even further.
Polearm Master does look strong.
We don't allow the bonus attack without a second Crossbow for Crossbow Expert. We're going with the intent rather than the RAW on that one.
