[Suggestion, Passes, Gems] Castle Pets or subscriptions
My two favorite parts of VIP Pass are the rationed gems and the rationed loot tickets.
It is like a computer enforced budget for family members and people using iTunes / Google Play gift cards
For same price as VIP Pass add new pets that drop the same amount in gems & loot tickets but replace The 2nd builder & x2 daily summons with:
Ent ( tree folk ) : Drops food
Gryphon: Drops recruits
Troll: Drops iron ( Devs have said future plans for iron)
All pets would have monthly & annual options. Players could have all, any or no pets active at the same time.
Ent + Gryphon would get you 6 tickets, 60 Gems, X food and Y recruits per day.
