I agree on this 100%. In large team games you will always have a player with sim city problem on side of the map and camp. The only alternative to fight this cancer is to rotate your troops on the map. I think we should re-think this ability or scrap it. The Brit player should be punished for sim city abomination!
No need to rethink it. This really breaks the frozen gameplay of "Sim City". The British Player tends to get REALLY bored when the enemy gives up attacking and the defences are taking up all the Pop Cap, not allowing the resources needed to finally go on the offensive. This is boring to fight against but is even MORE frustrating for the British Player who is now limited and forced to turtle until the enemies force is small enough to be taking out by a small force. Against a competant player, this isn't going to happen.
The ability to break down emplacements will allow the British to use more of their arsenal in high level play without screwing themselves over completely. Thankfully, the lack of refund makes it incredibly difficult to abuse.
Think of it this way...
The British Player must choose to dismantle their defences to get things going again. In other words, they destroy their own positions without you having to lift a finger or lose units! With no refunds, the British Player must spend more resources to rebuild.
The change was badly needed to make the British more fun for everyone.
That being said... I wonder it the build buff for Heavy Sappers needs to be nerfed to compensate for pontential abuse in 3v3 and 4v4 games, where resources are abundant?
