Ya I've purchased multiple troop packs for there intended purpose. Plus the flood siege for pretty much just the flood.
Idk, big sets don't need alot of figures if the context dosen't call for them. Drogon is a dragon. Why would it come with any other character exsept it's rider. The Kodiak siege cannon I guess is a similar set. Coming with pretty much just Alice and two filler brutes. But to be fair, what was the point of the brutes in that set exsept to add random figures to it.
Also I see now what you ment. The sets are now available for actual purchase and not pre-order. Now I get to question why my order hasn't been shipped yet :D since there's stock.
