Was thinking about Larian's homebrew Shove and how this would interact with the Polearm Mastery feat. Couldn't you just use your bonus attack to shove an enemy outside reach and every time the enemy comes back within the reach of your weapon, you get a free opportunity of attack? With the Sentinel feat also stopping the enemy from closing distance to within their own weapons reach?
How wouldn't combat devolve to something kin to a pinball game unless Larian makes evermore homebrew to accommodate their cheese?
It is possible in PnP too. Only difference is in PnP you replace one of your "blade" (assuming you are using a glaive) attack with shove. Here you replace your blunt side attack. Damage difference no mor then 6 (cause blade is d10 and blunt side is d4).
That is simply not true. When you shove, you can't attack with the blunt side of a glaive or polearm. Here is the description of the feat "Polearm Master": When you take the Attack action and attack with only a glaive, halberd, quarterstaff, or spear, you can use a bonus action to make a melee attack with the opposite end of the weapon. This attack uses the same ability modifier as the primary attack. The weapon’s damage die for this attack is a d4, and it deals bludgeoning damage.
