+1 PA can't make an unit pass from unused to overpowered.
And who says that TK's are meant to be used in closed maps only? They were meant to be the backbone of the Teutons, with the paladins and their siege.
If TK's are a bit less vulnerable to archers (well, remember that plumed get +2 bonus against Teutonic Knights), Heavy Scorps and Mangonel-line still massacre them. It's not like they'll become invincible with 3 PA.
And units like Paladins got both good attack and good pierce armor, it's not like it's impossible to do so.
