Just to be clear, the event map DOES reset each day on it's own. I was talking about the extra resets not being worth it. You have 4 tiles per lane, 4 missions per tiles for a total of 16 missions per type and each drops 2 items. The 1st 2 tiles are ok level wise so most people should get 16 currency items each run at least with most getting another 4-8 for the next tiles (the one that scales up to lvl 37). The last tile tho has nasty scaling, lvl 44-68 so most people will not finish it.
A good average estimate is around 20 currency per clear without losing too many tanks. 150 cores to reset the map, 250 cores for the 50 currency deal... common number is 1500. so 10 resets = 200 currency and 6 packages = 300 currency. With FULL MAP CLEAR you get 320 currency but if you cannot clear the lvl 68 missions then you EQUAL the packages and if you cannot clear the other missions on the 4th tiles then you are behind.
TL;DR: Do not waste time spending cores on map resets unless you are a mega whale and do not care about money.
