I haven't worked out too many details yet, but what if a new spell at TH8 (so above rage but below jump and as such, 6 spell levels) would allow you to "direct" your troops to a certain building for as long as it lasts, like the flare from Boom Beach. I'm pretty sure it would be quite useful to direct troops to the Town Hall or Air Defense, but of course they have walls to get through. No stats sorry, but what'd you guys think?
