The devs have nothing at all against EBs, and it's been said before that they loom in PIMD's future.
However, I can't imagine a scenario for them here that wont be stupid. "Get 100 people to kill a Titan" is a better concept than "Get 25 people together to... Um... Decorate a school function?"
As far as pwars go, while I have never supported them, I no longer aggressively campaign against them either. Just like farming, the overall outcome of a pwar adds money to the community. While some of it goes into upgrades, some also enters the tutor market and open market during attacks.
Say what you will about KAW, but there's a reason that PIMD constantly falls in the AppStore rankings while Kaw bounces between the top 10 and top 25 of its category, staying pages above PIMD (and leagues above FC). Just because you personally don't like something doesn't mean it doesn't aid the community and it won't become a favorite of a large group of players. PIMD EBs could add a layer of difficulty for the LCBC players who get tired of swinging on the top without much to do.
