Work on your defense and mixup. Learn how to tick-throw. 360 off 6A is a pretty huge gimmick since 6A has so much recovery frames during which your opponent can get a CH off you. No one's going to caught by it after the first time. Go with 5A, 5B, 2B, j.A, and j.B instead.
I noticed that a lot of the combos you ate happened because you were getting impatient and hitting buttons when you were supposed to be blocking and waiting for their blockstring to finish. Barrier-blocking can be a good idea but also learn IBing if you can. It's online, I realize that, but IB helps out Tager's defense a good deal.
EDIT: Also, don't move backwards unless there's a very good reason to. It's smart to not put yourself at risk, but you also want to press the offensive. If your opponent's just jumping back, then there's your chance to get in, which is usually a grappler's biggest problem (but especially with Tager) besides dealing with pressure and zoning.
