Please force collector upgrades
A lot of people only take from others by raiding, but never upgrade their own collectors. They consume but they don't give back to the community. This type of greedy play style causes the overall resources in the game to be much lower, and therefore, the average amount of available loot per raid goes way down for everyone. Maybe if only a small percentage of people were doing it, it wouldn't matter, but unfortunately more and more people are leaving their collectors unleveled.
Why should anyone upgrade? You get way more from raiding, so why bother right? Upgrading only makes you a bigger target. So maybe everyone should leave their collectors at a low level. Then we can all enjoy raids that don’t even pay for the army cost. :)
Well, I think Supercell should step in and help alleviate this problem by making upgraded collectors a prerequisite for other buildings. If you don’t want to upgrade, fine, but then you shouldn’t get all the other nice candies either.
