Queen walk is strong attack strategy especially to loot DE. I m using it from last 4 weeks and was able to get 2500 DE almost per raid after mastering it. My AQ is lvl 20 now. But this is not simple attack at all.. U need to choose a proper base, then funnel queen in and use rage / heist properly. I don't think it needs to be needed further.
Having gaints also in cc can give attacker a hell time... And placing point defenses and trash properly is the key in base design against it.
