Really? The only time I saw it being played was during a show, probably the game awards where all the character was doing was shooting purple blobs, blobs that didn't seem to react. It was such a bad first impression that I never bothered to look at it again.
At the core there's something good there yeah, like if you strip away all the graphics and just have testing block out graphics instead, it controls and plays pretty well, and even though everyone shoots, all of them are pretty unique in how they traverse and their special abilities.
However these designers are complete hacks and don't realise how to build on that core, this is something crappy designers do over and over, instead of building on the strengths of the core, they figure introducing challenge means
stripping away the core, which is a bad idea always since it means you're just punishing the player and not allowing them to play the very game you want them to play.
For instance there are snipers in the game and the game tends to spawn a lot of them, in season one they were really annoying to fight because they'd teleport away if you got a little bit close, they actually changed that so now you can actually get close, however one major issue with them remains, and that is if you get hit the entire core of the game is removed, all your traversal is gone, all your abilities are gone, and you are forced to hop/run around hoping you don't die from the next thing that's gonna hit you; this is an infuriatingly stupid decision on the designers' end.
Likewise they introduced "infused" enemies, which just means regular enemies with some abilities of the JL heroes, the batman infused ones just completely ignore your melee ability, which you need to restore shields in a pinch....another genius decision to strip core abilities for "fake" challenge.
But it doesn't end there, it seems with every season/episode that came, they found more ways to punish players, like just spawning some kind of hazard, like lightning or ice right on top of you, so you can't even stand still, which is hilarious because this season introduced a gear piece that has buffs that
requires you to stand still, but you'll never be able to do that in endgame so it's completely worthless.
I mention endgame because these things are never as bad during regular play/story, but the endgame exposes how bad all these decisions are.
Avengers did exactly the same thing funny enough, the core of avengers is actually a really excellent brawler, with really nice combo paths and combat feel, but then every update they just introduced more and more shit to make it harder to actually play, like stupid sonic enemies that completely obscure your screen so you can't see shit...
Whenever I see stuff like that it's clear to me they've got a bunch of designer who have no idea how to properly approach "play" and aren't there because of merit, but simply because of knowing the right people.
