People (D4) don't join war because they say they have nothing to do there.
But they do join Quest because they want Legends.
What if we had a Quest (I'd suggest Bigmaze since we focus on D4 ppl) every Monday or Tuesday (these days people said there is nothing to do), but only the nation with most victorys (during the past week) would be able to join. Also, to prevent leechers, you would need a minimun participation at wars. Lets say: getting like 2800 PWP.
In other words:
You help your Nation at War, you are able to do another Quest on a boring day.
2800 PWP means 40% of total PWP you may get fighting 7 wars a week. I dont know how many wars we have, that was just a guess. It probably will need adjusts...
I'd also suggest some improvement at war (even if its increasing stone's life/resist) because the current wars last less than 1hour, while It was supposed to last something around 2hours. That would also help on getting PWP. If people rush, It's hard to make it full
Help me to improve this idea if you like. If you dont, help me to fix it for you.
