if i were you i wouldnt use energy attacks, they can do more damage but everyone uses energy def (for party and solo too) so you will to more dmg whit p atk overall. And whit the right gear and +10 tickets you will be almost inmortal xD
well a warrior need more a croud control build for budokai I guess. So def decrease, pulling and knock down would suit better I guess. In solo they wont have a chance anyway I think. Maybe tricking a wonder would work. But to think about it in tournament the most people have status resist so grabbing someone can fail sometimes very hard and u get kicked out. I tested warrior quite a few times. He can be a very good carry (I swear if someone dont pay attention the whole team will fail). But on the other hand uf he cant grab someone he would just stand in the way.
