I believe I've been playing this since launch or close to. It's always been great and versatile but the grind is real. They offer many modes so gameplay doesn't get as boring as most other mobile games. I do wish it was a bit easier to advance without having to pay. Other than that I would suggest better tutorials and/or directions on how to advance the higher tiers. I could just be missing it though.

This is an amazing game it is really fun to make your own team of your favorite Marvel heroes such as Iron-Man, Captain America, Thor, and many more Marvel superheroes the only problem I had with the game was that it crashed a lot but now that problem is fixed so there is just one more problem I have which is just how hard it is to get specific items like the special tier 4 artifacts since they feel almost impossible to acquire one especially if you're trying to get it for a certain character

Fantastic game, but the multi-player is janky and unbalanced. My issue with pvp is that I get stun locked constantly. If my opponent uses their abilities faster, then they can just spam more abilities until I'm dead. I think making the change where most abilities can't stun or interrupt you would be a good change for pvp. Even adding a resistance to damage during abilities is good. Again, something like this is a little difficult to balance, but I have full faith that the devs can do it.
