I was working on idea for a kobold fighter both for the pathfinder and 4e games im in. Mahrek was born. in Pathfinder he'll be using an aldori dueling sword, the school of the weapon forces you to take on aldori as your family name. it's cool sword you can weapon finesee and wield two handed.
but in 4e there two fun feats for small fighters. one is scrappy which gives bonus damage when holding versatile weapons 2 handed, the other one which name i forgot gives you +2 to ac and reflex as long as you wield versatile weapon 2 handed.
