Tactics for the Stronghold.

A very interesting Castle, but I still can’t figure out how to play it properly. I start as Gurmi. Is this a good choice, or would it be better to play as Kreig, Tyraxor, Jabrak, etc.? (we’re talking about SoD, of course). For now, I’ve come to the conclusion that the strongest move on level 111 is to build a Goblin Town upgrade (even if the Wolves are already there). Am I thinking correctly? I’m not quite clear on the “technique” of taking the Bird Nests with minimal troops:confused:. Anyone have any tips?
