Eh, I found the P2W. It's on medium threads. No free player will ever get rank 4 battle armor if this doesn't change.

The game is otherwise pretty fair. Yes, the Jonin medal users get extra (as they should). It's not overwhelming. Massive expenditures can create a short to midterm unbeatable advantage, but few really spend that heavily. All of the ninja exam and PvE events can be beaten with freely available ninjas (up to ninja exam 80 is my experience).

The fact you can only buy medium threads or get them from cycling events (ie. mission box, random drop) just burns me. Well actually, it doesn't burn me too much - I'm a Jonin medal user. I can farm the 1,900 coupons in about a month. F2P can't and that locks them out of the single most powerful upgrade to the main character in the game.

Good luck in a few months...extremely disappointed about this.
