For that there are already watchtower upgrades. Upgrading a watchtower with another watchtower and replacing the upgrade is also making the game easier. I have plenty of watchtowers in stock, but no upgrade kits. Makes it a lot easier especially if it is done for multiple buildings, like you suggest. What will be next? Shrinking a WW wirh a WW cause you do not have a shrink kit?
To make myself as clear as possible, i understand the current buildings, the current upgrades, and how everything works. I've played for a long time. This isn't a complaining post, or begging inno to make things easy for us. I just have a ton of crap in my inventory I wish I could do something with. Even if I got upgrade kits for every watchtower in my city, I'd never have the room for the other 50 watchtowers or victory towers in my inventory.
So I was just thinking, what is a possible solution?
Does it make sense to upgrade a building with a building? I can see the argument that it doesn't make sense. I could also see an argument saying it does make sense at the same time.
I'm on the fence about the whole thing. If you have the item in your inventory, why not just makes it usable to modify it's duplicate is all I'm saying. Wishing well and rogue shrinking are a little different, but I wouldn't be opposed to the idea of one of those buildings being used as if it were a shrink kit. I mean it's just an idea. I absolutely don't want to give people a way around game mechanics.
Would it be more palatable for people if there was an ability to "trade in" items for their corresponding upgrade kits? It wouldn't have to be free, maybe we would have to earn the ability to do the trade in? Again, just some ideas to solve a problem. I'm trying to be constructive.
