Oh nooooo, the min 5 popcap cost. UK forces shiver in fear
meanwhile OKW having a good time waiting for KT because schwerer is gone
Bofors is 10 pop.
1 pop drains 1,5mp from your income per minute.
10 pop drains 15.
Over 5 minutes its 75mp and it just keeps going up, its a dead weight when opponent just ignores it and if its too aggressively placed, its not going to pay up for itself as, being as weak as it is, it can be easily countered by anyone who isn't strategically challenged.
This is not taking into account you being completely bullied by LV, leading to loss of further mp and map control, because your most potent counter can not even be built anymore. But hey, you sit on that one fuel tho while losing everywhere else, because 20% of your early game population can't even move.
Schwerer is a relic of ancient OKW design that forced them to go forward with trucks and consolidate around tiny part of the map. It should never be free convenience post rework.
The only thing keeping it SOMEWHAT in check is the risk-reward factor of potentially overextending and losing it, but if you place it reasonably, congrats, your cutoff is now immune to contest for next 15-20 minutes.
