Joker is not C tier (is around mid-tier). Shazam isn't that low either.
I am shocked you think Cyborg is better than about 10 characters and reasonably well rounded. What is your logic here???
Also, you completely ignored the horizontal arrows referring to overall balance. Sinestro is not extremely well rounded. He has difficulty with teleporting characters. Someone like bane is better rounded than you think as well. Yes he gets zoned out, but his dash and venom easily allow him to get around the worst zoning in the game if used properly.
This is pretty inaccurate overall I feel
1.) In the OP I stated Joker and Shazam are in those places because I don't know where to put them. I addressed that before any responses.
2.) Never been in line with the whole Horizontal axis thing. So I should add that to the OP. The whole well-rounded thing is making things a bit too specific. Especially in a game with interactables / stage advantage ect. You can be well rounded but at times a stage can completely nullify some of that. So I'll go fix that.
3.) I main Bane so I'm well aware of his roundedness.
4.) Cyborg being better since I'm taking out Joker/Shazam due to as I said not knowing where I want to put them. And omitting left and right. I'd say at best he's only better than 3-4 IF THAT. But he takes a definite higher level of execution than most of the cast and not necessarily for a good pay out. I'm aware of these things.
