Far as I can tell, Ardents and Battleminds are both melee classes - so being "punch drunk" is going to be par for the course for you.
I gave you Scale mail that can change into regular clothes if you don't like wearing heavy armor, and you have the option to take Light or Heavy Shield as equipment. At the moment, I gave you a Falchion with the Valenar Weapon training for +2 damage with it.
Despite your desire to keep enemies near you, I gave you a crap ton of pushes to keep foes away from you. :3
