First, Lightning Dance separates him quite a bit from the other masters I think. No other Resser master can move enemies with such ease (not taking the help of Belles or the Dead Rider into consideration here). In Ressers that can be quite powerful, if you throw the model into Yin and Izamu with Unnerving Aura for example. Second, your argument against him just say that the others are better at him at a specific task, which is fine, but you aren't pointing to why that makes him worse than them. He can do a little bit of everything; isn't that powerful too? Usually generalist models are view as being powerful. Maybe you think he is too sub par in his abilities to make him worthile? I am just saying that pointing out that one master is better at one thing than Yan Lo doesn't mean he is awful all around. Its like saying Ironsides is better than Rasputina since she is better than melee. Also, just to clarifying, this inquiry isn't pointed at you specifically Zfiend, I just quoted you to spring the argument
Really cool. This is were I think he is a bit overlooked in Ressers, as the other spirit master. He seems to synergies fairly well with the spirits overall.
Another thing, is Datsue Ba turning into Ressers' answer to Mechanical Rider? x)
