Would you remove limit on ships capacity/player?
no) you are just proposing a way to limit ship production, because every inactive player will max-out his ship capacity then lose additional ships. Playing more would not give you additional attack capacity, but people who just rely on their eco income would be able to buy more IP to get more eco to get more IP...
yes) it means players who idle for 2 month could them come back and bomb just about everything.
Which of these 2 solutions are you advocating for?
As it stands, pw is not focused on players but on clans/factions, so I don't understand your focus on people "who can only play a few games per day". PW is not a personnal quest, its shared with other people, a lot of them. If your faction can never play, either something is wrong with your ability to recruit, or you are not playing on purpose...
If factions were 3-people teams, I'd understand it can happen none of the 3 can play for some time. But faction is 1/5 of PW players...
