I thank you for making this post, i agree with everything you say. Your seriousness proves that these are actual issues with the game. They are trying as hard as possible to force players to pay money, and I'm not ok with that. I know they don't care what we say. I am stuck right now in game, my mech is stuck at all legendary, but I don't have any new items I can use to fuse them to mythical.
I also think the inventory limit is pointless and just frustrating. What's the point of it, aside from another thing they want us to pay for.
I want to be back in the top 10 again, I want to be a regain my rank, I want to have fun playing this game again, but I can't without spending a ton of money again.
