Full int, heavy armor... if you do so, your defence will be well balance, ideally for SOLO grinding. In party, you won't take much damage, or no damage at all and that case heavy armor is useless.
Also, it'll determine your sub. As a warrior, I'd say that you won't really use much of those skills as a 'lock. I'd rather go with cleric/bard and take light armor or just stay in robe, 'cause light armor is outta my style!
