I still feel new to Inj2 but have played enough to agree that yes, zoning is pretty prevalent in casual-level play. As others have pointed out, it feels possible to master ways to deal with it effectively--but if you're someone bound and determined to play a rushdown heavy style, sure, I understand why the game might feel frustrating and boring.
That being said, I do feel like the amount of hate that's been heaped on NRS about this is unjustified and kind of ridiculous. Consider that:
1. Character design is highly constrained by the source material. Most of these characters "zone" in the comics, so naturally they're going to zone in the game. It's nonsensical to think of Green Arrow without arrows, or Superman without heat vision. So zoning just kind of goes with the IP. It is what it is.
2. Pretty much all the characters have good tools of some kind to work within the zoning game, be it by controlling space yourself, countering enemy zoning, or using advanced mobility. The game feels pretty well-balanced in this respect (one of the reasons we saw such a wide variety of fighters at the IPS grand finals). Sure, there are some bad MUs, but not many. So it feels like most characters can be successful despite the zoning if their tools are used well.
3. Seems like many people piss and moan about all the "counter-picking" but I'm not convinced that's a bad thing. Sure, Inj2 does not seem like a game that really lends itself to exclusive character loyalty, but it also doesn't feel that hard to learn a few different characters, to cover for weaknesses and be prepared to counter-pick yourself. Isn't being adaptable and mastering several characters a sign of a strong player?
Anyway, my thought is, if you accepted those facts, gave the game a real try, and still hated it--hey, you know, no big deal. There are other games out there sure to fit your style better. I just wish more folks in that boat would accept it and move on. What it seems has really harmed the Inj2 community is when those folks instead look for any forum they can to whine and spread toxic negativity about how the game isn't what they want it to be (Not talking about anyone here, btw... the comments on this thread have been very thoughtful).
