So, how should I go on about clearing maps?
I'm pic related is my fleet. I'm at 4-4 right now and I'm pretty sure I could just go for it, but every time I clear a map my whole fleet's in yellow-orange and I'd rather farm some xp than wait 5 hours for them to be repaired just to repeat the same thing on the next map.
Should I just xp farm until I outlevel everything so much that I can just roll through or is there any alternative?
There doesn't seem to be any real benefit to clearing the maps in the first place, so I'm really wondering what I am supposed to do now.
