Infinite Tsukuyomi rebates were the fatal hit and now new server recharge rebates have become the last nail on a f2p's coffin. Most f2ps in the game are oblivious people who know nothing but constantly level up and use every bit of source to update power. Because jumping onto next server and starting over is extra easy. Plus there is no guarantee for taking your time in a server, no matter what you do, what you go through by your own efforts or strat such as collecting, coupon farming, freezing it won't matter at all. the gap is beyond astronomical. so if a f2p wants to play it anyways may the luck be them.
