Who said that you should kite him or use bugs to kill him? We know 2 tactics on EU to beat him, both rocks good on nm. With cliff walk you just made dangerous one a bit more dangerous, while was easy doable on open space. Since i am in good mood(and playing d3)... i am sharing them: 1. 3 tech sparky nade(20 cd, 7 duration, means you even have 1 free second). It was dangerous before, now its very dangerous cause of random charge+cliff walk. 2. FO Napalm. Just try it. After you see it once in action, you will understand that Air tree exactly underpowered Boss gets near 0.18 movespeed as i remember after stacking napalm. Well but it is still good to have sparky nade or force push to help a bit. You just need now some vision like tech's drones or recon reaper(road flares imo has small duration for this purpose) for 1 side and you can easly spam napalm at other side for safety.
