Just because TM can mop his local NRS scene with 80% of the cast doesn't mean he play them at a high level.
What I think you mean to say is that TM understands how to fight these characters at a high level with his mains. Which I would agree with, since his resume speaks for itself.
Tekken Master can play the cast.
The trend I see in this thread is that people can't see the game balanced as a whole. They look at their characters changes without over-viewing the total changes and seeing if they are in-line with the rest of the cast.
His list isn't perfect, but NRS haven't done a close to perfect patch either, with many attempts. His list is a step in the right direction (except -3 iceball, that is insane).
My character needs X or Y is only a factor if the other characters don't get touched at all. Kano doesn't need a safe brain-dead armor that he can throw out when -6 then run your ass into the corner for mix city, it adds nothing to the depth of the character or high level mind games because it is safe, its a no-brainer to throw it out randomly.
