You can shoot pikemen, just like you can shoot anyone else. You can facehug pikemen as a shielder just like you can facehug anyone. These are not counters.
And fighting lame with bigger lame isn't an option either.
you can shoot pikemen, BUT EVERYONE ELSE CAN CARRY A SHIELD/RANGE WEAPON
You can facehug everyone else, BUT SOMEONE WITH A PIKE IS WORSE BECAUSE OF 1 ATTACK DIRECTION
Apparently teamwork is lame, have you ever tried using a pike? Its the most useless fucking thing in a melee battle, but vs cav and vs longspear users its pretty much a hard counter, unless you're completely inept at warband. You can drop it after you're done with it, pulling out your real melee weapon to kill.
As a 2h, you can carry a fucking shield around to not get shot up, Pikemen are pretty much walking blobs of free kills for archers, while 2h can solo dodge/shield from arrow.
