wasup with the scouting thing to check the time interval?
Doesn't it take about 5 mins 57 seconds to regenerate 10% of the troops after the first attack n so on?

moreover, scouting the NPCs changes the hero and its level. It can get up.. can drop down.. I usually scout the d lvl 10 until I find a low level hero.. n then I attack till I conquer.. no scouting in between!!

however, this camp time thing can actually work great if NPC is at medium or long range.. never tried camp thing on NPCs but yeah it'll help for sure..!!
