Throwing around the word broken is... unwise. It's an un-seeable sweeping low. He had that in SC1,2 and 3. In Sc4 it was steppable but gave little combos (66K on normal hit, 11BA on CH). In SC1-4 it rings out.
The SC5 Version is just 2K by itself with no meter, a KND low which gives neither combo or ring out. To get those things, he has to spend 50% meter. If he wants to get combo's after, he has to spend EVEN MORE meter, 200% for BEx2 + CE. 200% Meter. Think about this. As far as I'm concerned this is actually a NERF, not a buff, or at the very least, the same strength but a re-purposing.
Please, think before you throw around the word broken. More importantly, just think about what you are seeing in general.
