Thanks a lot m8
Since I dont use these type of skills on my squads, this helps a lot. Pretty much the whole idea of using one team as pure support that heals you up is genius. Big Kudos!
Managed to make one pretty decent out of 5*, of which only 2 are event types, the rest is regular gacha ones (in the end did go and look at each and every single girl I have individually.). Lets see how much healing I can get from 1 girl who makes the nodes and 4 girls who buff that healing (if it stacks that is, I know for sure the nodes even dont on these maps, not sure about maps with more empty nodes, but on these particular ones, you wont get more than 2 empty slots usually.)
Edit: Ok so it seems the healing buffed effect does not stuck. Shame
