What do you think, is it worth and when to buy an extra scout? Do the prices change as you level up? I bought it from tavern for 600 gold and I'm not sure if that was worth the investment. Prize went up after that for a scout to 1600 gold. I still haven't upgraded all the necessary buildings yet and I'm not sure if I should regret it. Sorry for sounding like a scrooge, but I think it is rather high prize the level I'm in. (21)
How many scouts should I have in game to maximize the benefits? Would it be more beneficial and cheaper to buy a "savage scout" from the shop with gems? What do you think?
