If a monster gets knockdowned (Blade Arc), flys somewhere because a skill sent them flying (Blitz) or they get displaced by a skill like judgement, the other player has the monster at a different location and is hitting air, while I hit the monster.
We avoid using these skills, coz its so weird if u knockdown a elite and the AoE’s like Inquisitor’s Seal dont fit anymore so we both benefit from it. (And it’s weird in general if u see your friend permanently hitting air 
)
