Playing the matches is fun, since it is just Overwatch. Literally the same gameplay as Overwatch, but with 5 per team instead of 6.
In between is an assault of micro transaction manipulation bullshit that ruins the experience. PvE is hidden behind a paywall, except for the free stuff that is a retread of the seasonal PvE from Overwatch. I know this because I gave it some hours to see if it was as bad as people were saying.
People hate it because it was supposed to be an improvement but instead it was just another attempt to bleed the players dry. It might be the only game I have reviewed negatively on steam because the monetization really is that bad that it ruins the whole game.
