Most of us have been in that situation were we were losing and suddenly we see a chance to take out a really important tank, we commit all our available units and despite some losses we take out that really important enemy unit but then, when we are taking advantage of out hard won little victory, seconds later the same unit is again in the field and this time it proves too much for you to handle so quickly.
if he has enough fuel and manpower for another tiger or chruchill or elefant or whatever, then you were not just losing, you were losing very badly, so your chances of a comeback should be very slim
My idea aims to give the losing player a bit more help to come back into the game and/or punish players that don't use their resources properly and this idea consists of setting certain maximum limits to each resource type.
coh2 already has a lot of comeback mechanics, things like upkeep or abandoning
many people actually argue, that it is too easy to come back
