Two Weapon Wielding:
Im not expecting to be using two longsword and not really two short swords unless you where very experinced, Im thinking along the lines of Longsword/Dagger or Short Sword Dagger. There are specific dagger that where used like sword breakers etc, As a rogue fighter type build i would see character agility and manoeuvrability over the character being in full armour.
The dagger is used normally to deflect the enemy weapon so you can get at them with your sword.
Sheathe’s:
Also id like to be able to see the character i assume you will draw right handed id rather not draw from my Left side but from my right side, it is possible to do this with sword of the same length you would have on the left side. It also prevents you from if you got your shield pushed against you before you could draw from the left side, you wouldn’t be able to as it catches in the shield, but you could depending on the type of shield draw from the right.
3rd: Hiding Armour under clothing
I was thinking say we had a set of chainmail or chain mail armour that just covered the chest, i could put padded armour under it but also i could for example wear cloth over it, in some sense dulling the sound of the chain and also hiding it in some form, i think if we can do this with certain types of armour it would be good, im not expecting it to stop the armour its self from making noise as that would be very hard.
4th: Arrows and different arrow heads
Finally i would like opinions on if you believe there should be different types of arrow heads as different arrow heads where designed for going through different types of armour.
We have are standard broadhead
Judo Points which where for small game etc and so on
I believe having different arrow head types will be an important factor, especially for a rogue type character who if on the battlefield id rather not have in the frontline.
