Nah man variations definitely feel like you're splitting a character. Take Sub for example: MK9 Subzero he only had 4 moves, one was useless after the nerf, yet he felt like a rounded character and you didn't feel the base was lacking; the special moves complemented his buttons well. MKX Subzero only GM was good because clone, the other variations had a lacking base obviously because they wanted to compensate for clone being a major neutral breaker. And even GM was quite polarizing because in MUs where clone gets shut down easily he suddenly becomes shit.
MK11 Subzero the "best" variation has only 2 special moves ffs. Thin Ice is ok but you always feel the character is lacking something, especially with the 2 useless moves he has. Avalanche is nice until he plays against chars with fast fireballs that stop him from getting out the clone, then half the variation is gone. When I want to play Subzero I have to choose between clone and air axe and it sucks. All variations feel like they're missing something.
Then you have other problems like Sun God losing his best tool with the B1 nerf because War God was stupid.
Variations bad
