That's the thing. As Yammy gets angrier and angrier, his strength and spiritual power are going to continue to increase. He's already implied that he can transform at least once more, so long as he keeps getting angry. Also, each time he transforms, all of the damage he has sustained heals away instantly. If he didn't give Kenpachi and Byakuya issues before, then he will soon enough.
