Ok, so I'm just enjoying my time with the game and playing lots of different characters. Right now it's Bane, Swamp Donkey, Atrocitus and Black Adam. I just started playing with Grodd because he's a cool ass character.
So, I came here to learn Grodd because after a little in practice, I did not understand what the character is designed for. No pressure, no safe strings, gaps, etc. So I came to you guys. First thing I see is this thread, and after investigating all I can say is I'm sorry people. You guys have it rough. Swamp Thing also has some STUPID tight links, that don't even work on a lot of the cast, gaps for fucking days, and other shit that really makes him not fun to play outside of super casual.
What he does not have is NECESSARY shit with a massively high level of execution with zero pay off. So I think I'll come see you guys again after some changes, if they come. I went back to practice after reading the OP and tried punishing those gaps with Bane, and GOOD GOD can he make Grodd pay.
Anyway, you Grodd mains are awesome, I wish you great buff luck in the future.
P.S. I really like Injustice 2, a lot. But I have a huge problem with the disparity between characters. Within my 4, Bane is very good with some really (really, really) hard matches, Swamp Thing sucks, and with Atrocitus and Adam I feel like I can just do whatever the hell I want most of the time. There's making your characters feel and play unique and then there's "what the hell are you thinking?"
