One, matchmaking is NOT based on skill no matter what you say and the vast difference in hangars in numerous documented battles show that 'approximately' means nothing 🤦♂️😅
Two, paid content is locked behind a paywall that consists of predominantly legendary items and is far superior to items that f2p has access to so there's no way the grades are remotely close to the same on most occasions. A perfect example is buying nomad (not accessible to f2p) and then just completely destroying your opponents. Nearly every single one who has nomad has high wins, places very high in tournaments, and easily completes events compared to f2p. Stats and numbers don't lie...
Like I said and if you took the time to actually read and understand what I said, it's not out of the realm of possibility that a predominantly rare/epic hangar can take out an all paid legendary hangar but the odds are not in their favor. That's a FACT whether you want to admit it or not. Otherwise, there would be zero reason to buy new items or try to improve the hangar if someone is looking for a competive edge.
The game is p2w as clearly defined by your own link and the current game dynamics which also includes the atrocious matchmaking that is clearly designed to entice players to spend, not create a fair game experience...
