Pretty sure there are many threads like this, but I may as well make my own. Right now, I'm done with mission 8, but I haven't 3 medalled the missions after 8-1 due to the hard-hitting bosses or RNG arrows. I have also finished the first phase of the current event and some of the other dailies up to normal difficulty.

I have a few questions on what to do from here on:
1) What is the best and efficient map to farm for manyus aside from dailies?
2) What is the minimal level to 3 medal the mission 8 maps and probably the second phase of the current event?
3) Which girls do I need to work on below:
