In terms of speed in growth, Would it be best to grow a guild hansel by building regular buildings, ie: T4's lowlands T5's highlands, and then drop build? Or would growth be achieved faster by just doing the guilds, and foregoing the T'5's and 4's?
Best is to go beastiaries and guilds until the 900 mil land. Then convert everything to lvl4 guilds and 1 war aviary. Or you can do a CoE but I don't see too much benefit there for the cost. Key is to get that feather sword. And low level GHs do very well at getting equipment drops. I got both the diamoneferous and abyssal in one drop on my first try at FoD
It's a bit of a double edged sword. I think SDTs are better than ADTs because it's been my experience that they add 1/4 the plunder of an enemy hit over ADTs. But I've only tested lowland towers for this. I don't know what the factors are for T5 and T6 towers. I'm just guessing they follow along the same lines.
