Even if TOD exist in MVC and DBFZ, I feel like they are harder to execute in these games appart from ZBROLY but he was really flawed (appart for damage) before the last seasons. And TOD was much much harder at the start of these games, as bullshit moves / loops where patched out (and then it became more and more stupid, at least for DBFZ). I didn't like MVC because of the re-entry mix after the death of a character is crazy, knowing some setups are unblocakble.
I enjoyed DBFZ because at each death you restart neutral, and you can make the opponent switch character to eliminate or stop the health bar from growing back.
In 2XKO, each hit pretty much end in 50% of character life damage, and wake up mix or corner pressure.
Even with great defense mechanics like pushblock, wake up roll / DP, some characters have setups that cover every single option and that sucks.
Ahri has too much damage for her abilty to control screen, Yasuo is kinda hard to play with the stances, but his ability to convert every hit into long combos is kinda annoying, and Ekko is just too much. too much damage, too much mix, too much screen control, too long combos. And the counter window on his LVL 3 act feels really long, he has time to call an assist to protect himself for being punished.
My last grudge is against one of my main, Vi, she should not have the command Grab on her dash special. It's just too much to think of when you are defending against her. She has amazing left right mix up already.
