We playing the same game, man? His specials are OP and he's probably the easiest character to chain moves with. Kabal's always been broken, hell he was broken in MK3.
How are his specials OP?
Spear - Highly punishable. Only good for armour on EX, anti airs, and in combos.
Tackle kick - It's okay, I guess. Nothing special.
Teleport - Highly punishable. Honestly, if you can't deal with his teleport, then maybe you should think about learning to play the game properly.
Hellfire - I mean it's a decent move, but it should not be a massive problem to you if you know the matchup. It's a really character specific move. It's useless against characters like Kung Lao and Kabal, but it's good against like, sub.
So how are his specials OP?
And about how easy it is to 'chain moves' with him... easy execution does not mean that he is a good character. Skarlet is a much better character than scorpion, and she is one of the hardest characters execution wise. It's about the tools he has and he is severely lacking. His normals are slow.
Instead of just complaining all the time, learn how to fight against characters. If you whine and whine, nothing will change. If you actually open your eyes, sometimes you realise things aren't as good as they seem. There are legit OP characters, like Kabal, Kenshi and Freddy and then there's characters that people just complain about because they're too lazy to get their shit together.
This exactly what happened to Kano, smh.
