Yeah, I agree it's just need a better money strategy. Killing the adamantoise for platinum ingots is okay but when they dont drop I want to scream and when they drop a Trap it's nice but then I can't make money either because I have to save the Traps for ultimate weapons. I have Lv. 100 Nirvana (Malboro version) and a level 60ish Omega (Lionheart Version) but other than that none of my people have over level 18 weapons. Farming money is much harder than farming full CP levels for everyone.
Plus when the adamantoise don't drop anything you then have to go refarm 3 CP to be able to summon again if you don't kill it with death in the initial 20 seconds of the fight before you need to summon to get your HP back up.
