Well I haven't spent a dime on the game and would like some new 5 ranks and know that getting a 6 is nigh impossible without money. I have plenty of characters from the events that still need development so I guess I can fall back on the 5 ranks.

BTW, I glanced at youtube and saw a supposed guaranteed way to get a 6rank from the free gacha by this method

1.Don't do the daily free pull
2.Take the team through a map run
3.Spend 5 fgs on the premium 1 pull
4.Do free pull a
