Best place to use units?
I’m f2p and I won’t have enough units for July 4th. I have a few options:
1.) Do arenas and wait for cyber weekend
2.) Open a few cav crystals.
3.) Use the units to explore chapter 1 in v4.
Don’t really have that many good 5* so cav crystals might help. I also don’t have ghost and heavying in the corner is tricky so v4 should wait till I get ghost.
