ABSOLUTELY P2W
Let's me put this out there before the rant.. the game is fun but unfortunately it's pay to win.
You get to a point of about level 35 and youve completed campaign all the way to second last boss on brutal and your having a hard time and then energy becomes a big issues so now you have to wait or pay for energy to grind and earn! So hear are all these ads for armor sets,rank chicken and crystals
Soooo they want you to pay for energy and then artifacts and everything else to get good ranks on a leaderboard??? So you pay to grind and pay to boost there is paying in every corner of this game and for the people who can't realize it...
Mod note: Edited out ranting and veiled profanity, please do try to be a little more respectful.
