Fun at first. You will quickly reach a point in the ladder where it is quite literally impossible to compete without spending embarassing amounts of money due to the way crit works. You get 4 keys per day to play co op where you can either whale to succeed or pray that you get carried due to the difficulty. Not much else to say, this game is pay to win in its purest form and the outlandish prices on all of the packs suggest the devs are perfectly aware.
