Even so i'm playing with my Holy Team (stongest one atm) i don't have any problem against the Red one, but Blue is really Hell himself (my team can survive only 1 Rage Overdrive, but then any AA from her and i'm out) and i don't have any healer (Summer Brynhildr doesn't count as one and i don't have Andromeda.) When i create a Raid i wait till 2 people enter to my room to start the battle, idc if i had the MvP, as long as i get the reward i'm fine with it so is a fair enough Raid for me.
I really look pointless to go with a Healer or any Water Kami i had, because i don't have weapons so it's fair enough, and even if i heal (Using Cassiopeia + potion) in Blue all my team is going to be wiped out on the next Overdrive because she hits like 5-6k damage lol.
By the way, i'm a bit confuse about Raphael -Damage down, is A-frame right? Because everytime i use it and there's a Joan misses.
Sorry if i mess with my english, is not the best atm.
