So im lvl 43 and my survivors average level i will say is around lvl 36-37 and im trying to find the most reliable and fastest way to get up to lvl 55. So far (since i have DMU) ive found that having the book : taking the long way home with 100%EXP and 134% return time increase (dosent really matter) stacking with letting enough double exp stack up for one or 2 missions will maximize my xp gain.
but somehow with my strategy i feel that i could level up faster. If you prescribe raiding i personally dont find that to be reliable enough since im not that good. So do you guys have any ideas on combinations that could possible speed up this process any further?
