One of the main concerns for lower level players is getting zeroed when you are starting to build up. I bet everyone agrees that getting attacked 100 times for literally no reason is dumb, especially when you lose SO much progress (like 2-3 months of work). Making PVP cost brew seems kinda natural, as attacking monsters cost brew. Even making it cost like 20 brew would be pretty nice. It doesn’t really hinder higher people trying to attack over cap people and it doesn’t provide any unfair advantages to anyone. As well, you could implement a higher brew cost per town hall lower to further incentivize attacking similar town hall/progress players - just like how attacking someone 5 town hall levels or lower doesn’t get points in slaughter events.
