I just finished building weather files for all the terrains in rotation. All except for mine bowlma, are 10x10 or what is called small terrains. Bowlma is on a 20x20 grid but the combat area is 10x10. Unless we get an influx of players so 300 a night are the norm, I suspect 10x10 is it. And at prime time you see less base taking even on a 10x10 but, you come in the next day and the map has been flipped or most of your countries bases are captured. Late night with low numbers no one tries to stop three guys with an M3 from running through a country capturing feilds.
There are two possibilities here, the M3 test of running supplies causes Hitech to stop allowing GV's to resupply towns which helps reduce stalled out base captures. Or he doesn't touch that and instead reduces the down percentage of the town which could also reduce the bad habit of fighters circling for vulches while the M3's run in supplies unopposed. A normal scenario is you have 10 guys in fighters circling the field after the town is de-acked doing nothing. One con ups, and all 10 are fighting over each other to kill it and hoping for more. M3's just run into town behind them and bring up the guns and maybe the town. But, the vulch light is lit and the fighters don't care. Sometimes more enemy cons up and other show up and chase off the fighters and kill GVs stopping it. Other times both sides stall out while the M3's bring back up the town, and instead of pulling back with a second field to go after, the bomber guys show back up and try it all over again. Missions often had plan B for things like this versus the loosy goosey show up with the herd to vulch if the bomber guys are hitting the town thing these days.
So where hoards used to let 30 guys at a time avoid combat and Hitech had to change the game for that, the current style of prime time loosy goosey, maybe we will, maybe we won't base captures, needs something to change the dynamic. When any country gets on a roll and players are energized by their quick successes. The quickness of the base captures doesn't let them stall out and get bored killing their enthusiasm.
