I do own Yan Lo, but I still find others useless. I'm not gonna start playing Yan Lo in TT, when all my other models, are Resser. If I'm going to a tournament, pretty much all tournaments are Faction locked.
And you're making a great point and showing the big problem - TT players will want Wanyudo, as such they have no good reason to buy Minako and Katashiro, as that just leaves them with the same problem I had originally.
