i have a double wide moat, with bridges, spikes, and enough defense that most raids, end by the mobs running towards my base and dying from the defensive structures. most if not all raids ive encountered, its 1 or 2 red trolls, and maybe 1 other mob. Ive killed allot of everything in the game, so this theory is busted, as in.... you shouldnt be getting entire groups to raid your base, if the rest of us are getting 1 maybe 2 mobs. and other mobs hunting..... when a troll raid happens, its only trolls, not sure where you thought 7 different mobs would attack at 1 time.
