Scouts and assassinations are used to gain control as they generally burn a larger % of the targets troops than your own. Stealing burns a higher % of your troops in exchange for generating plunder.
Advantage you get to choose when you come out of ko between 7-13 minutes. Random you randomly come out ko between 5-10 minutes. Classic is fixed you always come out of ko at 10 minutes.
Not in Primal Wars, if those are still going. But as far as I know, yes it does. Although LL wars may just be build stats with no bfe or BFA counted.
Ps1 in low tiers is great as it's easy to pin and with decent allies and equipment you can usually hit most people easily. That's it really for troops. In terms of spies ps1 is great for controlling and is better at chasing ko over ps as if their troops are pinned it's unlikely they will "leak". Stealing is also good plunder from full spies but doing this loses control generally although steal ko pays a lot it's just not as easy to pull off.
Is other questions about kaw (farmers, behaviors, pimd players, valiants, links, mods, devs, etc.) was still asked here?
