Same issue, I love Kotal but he is hot trash.
Most of the characters lack in many ways tool wise.
In mkx I played characters with rushdown tools that also had footsie range and OK zoning and decent pokes.
I played trap characters mostly with all mentioned above. In X that was very easy to find. Characters with either: 50/50s, Plus on block and range or characters like Cassie with amazing frame traps, mix and very solid range.. Cyrax was my main
But in MK11 its like characters can only have one if the following:
Mix, Frame Traps, Footsie tools and strong counter zoning, combos.
Error is very well rounded but his lack of comboability has me board with him quick.
I use everyone in MK11 but none that truly gets that final main title maybe when kotal gets fixed..
Right now I'm mostly using Cassie, Erron, Kotal, D'Vorah, Jade.
Cassie has great staggers, number if hit mix, good zoning and OK combos midscreen and tootsie tools but lacks traps, pokes, true 50/50s. She is very good just not what I really want.
Erron has great neutral, good counter zoning, good pokes, good mids. Lacks comboability only being able to combo from his LnL special move, he also doesn't have real plus on block frame traps aside from D1 into 21212 and 114 but 114 is only plus 1 so his 11-13f mids don't really frame trap at that range. Very good character though.
I could go on but I feel characters are missing what I'm used to in previous mk games and the comboability is lackluster witH many limitations compared to MK9/MKX.
I have hope for Shang though. Please NRS let him have mix and ground skull launcher into combo with decent projectiles.
The morphing alone is enough for me to main him but weather I get board depends on how he plays and how limited his combos are. Weather he has solid mix game to open up, if that's staggers, number of hit or 50/50 I'll be happy.
I like characters that are JacK of all trades master of none.
