I will take the opportunity to ask the developers about their opinion on Chain-Grab effectiveness.
What do you guys think about inescapable Chain-Grabs that deal a high amount of damage?
Fox example, I don't see anything wrong with being able to Chain-Grab a character from 10% to 50 or 60%, but CGs that deliver higher damage than that make me feel uneasy. Obviously, we could point out to how hard it is to execute the CG, but where the dev-team believes to be the balanced amount?
Personally, I wouldn't like to see CGs that deliver more than 50% Damage, unless there are trustful methods of escape.
