VIP and iron in general becomes less useful once your town is completely upgraded. I don’t mind VIP for the gems and emblems, but it may not be enough for them cost as the second builder is there best part initially.
Let the stronghold have an “interior upgrade” option at level 25. You can have one or two running at the same time. They use a builder and take 3-7 days to complete. They use up to 2500k iron per “upgrade”. They don’t actually do anything to the stronghold, so can be done infinitely.
Each upgrade can produce a choice of:
- Epic troop token
- Epic hero token
- 100 ninja tower coins
- 5 costume keys
- 10 challenge coins
- 100 Atlantis coins
- 100 Legends coins
- 100 Valhalla coins
- Etc. as more portals are created
This keeps VIP useful and thus SGG gets $, gives FTP one builder to take part, and makes iron and builders useful for players that are done upgrading buildings. A win for everyone IMO
