The concept itself is fine. I don't enjoy it but I'm kinda forced to play every season cause I want the battlepass rewards. After I've gotten everything, see ya.
Don't look at it as a competitive mode since there's no balancing at all. It's just one of the many fun modes the game provides.
Seriously, I'd like to win or even lose faster in Crystal Conflict to get my battlepass sooner. It's a disaster to join a match where everyone refuses to give up and congest the crystal for 10 minutes.
Even if you begin to enjoy the competitions, then you'll learn that there are people out there using triggers to auto-refresh or give themselves all sorts of nasty advantages. Meh.
