Is this mission possible? You're only allowed to use knights and rangers, but half the mobs that spawn have a high degree of evade ranged, meaning rangers suck. I have high level units (lvl 55-58) and upgraded all legendary bows and swords, yet I can barely stop the first wave of worms (literally the first wave of the mission already almost kills me), and the second one I have absolutely no chance at stopping. Am I missing something here??
