Help needed in creating a roleplaying-traits for warrior based classes

[Titus Marcellus Scato]

Beserkers wouldn't be immune to weapons, only immune to pain. So they would keep fighting until they are killed, while a normal warrior would keep fighting only until he is badly wounded. Also Berserkers would be very poor at defence, armour class would be very low, since they are in too much of a blood frenzy to care about protecting themselves. Instead they would be very good at attack, and might get an extra attack per round, since they would be striking more often instead of cautiously parrying blows from the enemy. The only defence a beserker has is to kill his enemy before his enemy can kill him. The fear effect of a beserker might give him a higher chance to get in the first blow as well.

Naked fanatic would have a dexterity based boost to his armour class, able to dodge better since he is not weighed down by heavy armour. But that might not fully counter the drawback of not having heavy armour. He also will probably get in the first blow.

Shield bashing - all warriors know how to do this, not just Romans. But warriors with short swords have a chance at combining a shield bash with a quick sword thrust in the same attack round, which warriors with hacking long swords can't do. Although a hack with a long sword will generally do more damage than a thrust from a short sword.

Long swords can do bludgeoning impact crushing damage (like a mace) as well as cutting damage if they penetrate enemy armour. While a thrusting short sword does not do crushing damage, and thus will do no damage at all if it doesn't penetrate the enemy armour. So you can batter an enemy into unconciousness with a long sword even if his armour is too good to penetrate (after a great many blows), you can't do this with a short thrusting sword.
