D&D 5E Paladin Pole-arm Master damage

You say your concern is that "the build is too powerful compared to the other PCs."

What are the other PCs in the party? And what sort of focus does your campaign have on the other two pillars of the game (exploration, social interaction)?

I dont know any DM that allows Tunnel Fighter. That thing is broken enough that even seasoned players don't ask if they can take it, they just assumed its not an option.

Not sure about tunnel Fighter, but I think everyone have just one reaction to one AoO. No unlimited reactions in game.

Broken feat is broken. Have the gods strike down the paladin for being a cheaty cheater.

The issue with Tunnel Fighter is that in combination with polearm master, it allows unlimited attacks on enemies who approach so the real problem is the extra damage from divine smite multiplying across many many attacks.

The issue with Tunnel Fighter is that it is broken. Just remove it and your problems will be gone, no need to fix other things.
