He only sounds broken on paper, things like his health, his combo rate, proration values, and starter combo ranking could be a means to balance him.
Frankly he sounds very momentum reliant like Valkenhayn or Tao.
Then there's questions like how much heat is taken per d move? Does it differ depending on the d move? Are they safe on block? Is the heat stolen literal or methodical (can he steal heat if the opponent has none to be stolen)? Does Terumi have a DP? How many wake up options does he have?
All we know is that his offense, particularly his combos will be very cruel. We know nothing on his ability to safely pressure the opponent nor how good his defense will be.
I'm personally scared of what his OD will be.
