Unless you want to be a master of all stances (what is great, I guess), it seems to be really unecessary to cap all of it. If we take a look at stance table, we find this:
*Tiger wins against Mantis (+3) and Swallow (+1);
*Dragon wins against Tiger (+2).
So, considering combat, what is the point on capping Mantis, Swallow and Monkey? And, when we think on basic stances, why to cap Crane and mongoose?
Lets discuss it! :)
