Heres my thoughts on my limited time overall that ive played T6.
1. The damage is a bit over the top with almost every character in the game able to take 50% of life off you with walls without rage.
2. Due to point number 1 I will say that that does balance the game in a sense since almost every character has the same opportunity to take away a huge amount of your lifebar. Back in DR only the mid tiered and higher characters like Bryan, Feng, Mishimas, Julia, etc could do that much.
3. The damage that characters do is no different than DR. Combos without wall still do around 40-45% across the board with all characters. So if you thought DR was ok gameplay wise then i dont see how you can see T6 being a lesser game. The bound system does allow for longer combos compared to DR but because the opponent falls faster in juggles and i think higher damage scaling in juggles counter this so the damage ends up the same.
