please donate from armycamps first
donating from the camps first opens the possibility of rebalancing the army by just donating the unneeded troops. the replacement would be the first troops in the training cue.
but as it is now, donations are taken from the training cue first. so if i have lets say 15 baby drags in the camps and some more waiting somewhere in the cue, but i only need 14 of them, i'd have to delete all prebuilt baby drags from the cue before donating and rebuild them thereafter.
not a big thing but annoying sometimes.
i don't see any downside of this little change.
