damn left flank

[Kraxis]

You can also argue that since it is your unshielded side you have an easier time turning into a flankattack, that your weapon will always be at the edge of the turn. Generally in a 1v1 people with shields tends to walk counterclockwise round to get their weapon into range. So maybe this was something that was a leftover from Heroic times where chieftains would duke it out with each other in 1v1.

There is no evidence of any lefthanded warriors, meaning that all lefties were forced to use the right. It didn't cost them all that much really as you quickly learn to use the other hand. I'm lefthanded, but I use knife and fork like the rest of you (but if I have to cut wood or something I always use the knife in my left hand), and I use the mouse in the right hand as well.
So a lefthanded legionary would not be any different from the rest of them. But imagine if he used his sword lefhanded... That would be a major disruption in the unit. He and the guy to his left would likely injure each other in a battle.
Of course it would like in boxing be an advantage in a 1v1 with a chosen enemy (which still happened).

One reason left handed people were thought to be untrustworthy is that since you shake with your irght hand you couldn't stab the other person or pull a sword on them, but if you were left handed you could easily stick him in the gut.

I don't have evidence of this but I was told this by a reliable person.

The answer to all your troubles:SLINGERS
Just put them on you left flank and they fire onto the unshielded side of enemies.

I have heard a slight variation of this idea which states that shaking hands with the right hand evolved as a gesture of good faith. By presenting ones empty right hand you openly declared that you were not carrying a weapon in it, and by mutally clasping each others right hands you were actually preventing each other from drawing a weapon.

I recent used this idea in a roleplaying game I run.

Which again means that grapping the other's hand with both of yours is even more of a friendly gesture, as it stil is, because now you can't even use your left hand.
