I read the last few pages.
CT was a vastly different game system was as well. With things like Danger mode being there for every burst to discourage bad bursting. Tager used this more than anyone since if he baited a burst (LOL autoguard bursts allow jump cancel IBs and whatnot) he basically automatically won the round if he had meter.
A Heavenly Tager Buster?
Potemkin didn't even use it for Antiair. Basically due to the fact it wasn't invulnerable and was able to be hit out of from the air. You used it to stop certain situations and lockdowns or you combo'd into it to get that minimum damage. Well, Potemkin was also designed to not be a grappler. There are tons of characters in the fighting game universe that aren't grapplers but control and dominate the close up game really well. Most of these characters hit really hard and have beefy as fuck normals that were also fast.
Why is Tager bad?
Remember in CS? Mori said that a grappler in the higher up tiers makes a game not fun. He wasn't referring to Potemkin. He was referring to early days Street Fighter 4 where everyone and their mother thought Zangief was god tier. Or Battle Fantasia's arcade edition where Donvalve had infinites on everyone because they forgot to put in pre-jump frames as being unthrowable.
So Tager is a grappler. But his normals betray him and he has no reversal that is actually useful. Lariat? 50 meter for one sure. And then it does mediocre damage for a super. 360? With enough practice you can notice the animation and stop attacking and jump out. Atomic Collider? Gets beat by most jumping moves anyway. 720? It's a true reversal, but in a losing fight you'll only get one. Or you won with it. Either way it's a 50/50 that will either win you the game or lose it.
Look at Super 4 Gief. How many times do you see Vangief depend on the 720 to win? Nope, Gief has footsies and combos. Look at Tager. He has no oki to the point that Gief has. His knockdown power is weak, he has no crossup (Don't give me j.2C as an answer either), and you don't need to respect an 11 frame 360! Tager is forced to rely on one move. 720. So therein lies gimmicks to find ways to land 720s consistently to put you in positions to win more games.
Most people who mained Tager were all about landing the 720 since it's little work to land over 60% because the opponent didn't hold up or messed up a combo or blockstring.
Reverse beat normals
Tager getting reverse beat gatlings wouldn't change anything other than oh i dunno, giving him an anti jump game? Frame traps? But those gatlings wouldn't help nearly as much as a level increase on moves or faster startup pokes.
Make 5B 5C combo normally please. So we can have 5B 5C HELLSU FANGU combos.
