According to the OP's post, he has never been fighting Mongols or Timurids ;)
He'd die within a few minutes with that "tactic"

Your tactics should depend on the type of units you are facing and your enemy tactics. If the enemy likes to advance towards you, hold your line instead of forcing a ehad-on charge on both sides.

The entire beauty is to minimize your losses.

BTW, ever noticed that conventional tactics are bad against mongols? I killed all their stacks by attacking them on any terrain tyype using massive amounts of ranged infantry (moorish peasant xbows or english longbows) backed up with some heavy infantry if they dare charging in. Works like a charm.
