Yes the chains are bad on block, us Haz's are told NOT to chain in on block because it leaves us open for a CH AA combo best thing I could suggest is use something like Ragna's 6A *using that as an example cause it's CH me into a combo before* Or keep guarding and the best thing to do in that situation if you do keep guarding is to standing guard unless you see them bout to land and haven't j.B j.C or j.2C which the standing guard will prevent from hitting but if they're gonna land switch to crouching to block the 3C or 2B that most likely is about to happen.
