I'm grinding for souls right now and was wondering something about experience gain.
I'm leveling a 7* right now. Is it better too...
1. Just deploy the 7* and gain the 675 exp from the quest.
2. Deploy a 2*, 3* or 4* unit to level them and then feed them to my 7*.
Which method gets me the most out of my 675 exp?
Also, i forget often, what is the best level to raise feeders to for max exp gain.
I thought it was 2* lv4, 3* lv8, 4* lv12.
