I played a Polearm fighter in Adventurer's League and it sort of sucked with TotM. I was thinking the 10' reach would give me lots of opportunity attacks and allow me to limit enemy movement, but it basically boiled down to whenever the DM figured it was appropriate (which wasn't often). It basically negated any strategic positioning on my part during combat.
Overall I have no problem with TotM, but some of the game rules are less useful when D&D is played that way.
