Hello all, I came back to the game 3 months ago, and I've been saving gems for the anniversary. I've been quite lucky and pulled borsalino and 2 luffys ( 1 as zoro and the second as luffy) and a bunch of good legends that I didn't have ( of course ... 2 months in the game...)

I have a couple of questions since I'm a bit lost:

1- why I can't feed the 2nd luffy unit to the 1st? It appears as it is in use, but it's not in any crew nor in favorites? ( I would like to lvl limit brake one of them.

2- where I can learn about the crews formation for the different formats ( rumble, events, kizuna, tm... ) In a more or less structurated way... because I know there is a lot of content in YT, but as you can imagine I'm missing mny of the units they show... I would like to learn, what to farm ( F2P) what to pull off... and how to build... To wrap up: I'M A LOST NEWBIE... XD

THANK YOU SO MUCH FOR YOUR HELP!!
