I'd like something of the effect that attacking the rear city strat will impact the entire country, but on a very small scale. Similar to now, there really is no noticeable effect for small attacks. Any real effect would require a large scale mission. However, I'd like to take away the ability to re-supply the strat. If a mission gets in and hurts strat, it is usually re-supped and back to normal in a few minutes.
It is usually not resupplied. I have yet to see anyone doing that, which does not mean that it doesen't happen, but it is very rare. Having watched the strats very closely during the last weeks, I have not noticed any down time shorter than could be explained by the auto resupply. And in fact, you can't resupply the City at all.
For both potential attackers as well as defenders one thing can be said: No one
cares for it. Actually, only very few players do know how the strats are working at all (I am also suspecting that this had been true years ago for the 'old strats', they were probably mostly attacked for points). The factories pop up again quickly, just because nobody cares to bomb the city first.
Almost all attacks I have seen by other players were totally uncoordinated and hitting the wrong targets, dispersing the bombs seemingly random all across the factories. Of course this has no effect.
Today I did a few runs on rook strats. First I bombed the City to 24%, then dropped the ammo factory to 48%, before I had to abort my mission because wife was hungry (imagine that!). Even with the City not being really down (I messed up one attack a bit), the factory stayed at this reduced level for two hours.
A small squad of only four capable players could do a lot of damage by combining starts attacks and porking front line bases...
