Start using a shield dude.. I have +2 Heavy Kite
Not having a shield is better for a 1hander when fighting: 1handers, 1handers with shield, 2handers, 2handers with shield, polearmers, hoplites, archers, lancers, 1h cav, 2h cav, HA, HC, HT and throwers.
Only class that's more difficult to fight now is foot crossbowers.
