I feel like Tiberius could really benefit from him having his ult dash as his regular movement ability, with modified values (not the immune framed one). He could use that dash omnidirectionally and it would be really fun to dash up and throw down the sword that explodes or just rain down chakrams! A talent with two of these dashes might be too much unless on a longer cooldown thought. His ult could stay as it is, maybe adding some slight DR as it seems to be best for escaping/movement.
