Watched only 30 sec of video in which he targeted 5-6 healers in row, amazing skill in mass pvp i would say, out of all those ppl to target just healers
He probably has assist macro for assisting the shot caller of the party or just macro with important targets like healers and maybe crester.
He made a lot of positioning mistakes same as healers from the other side, if you check the video on 0.25 (I watched it on that speed) you can see that he targets people in front of him, he didn't press any macro or anything like that, he just goes to target someone from a big group of people to AoE them because he doesn't care much about targets on hero zerk + 101, he targets always people right in front of him and people that is logic to target in those fights, if he picked up so many healers it's due to their awful positioning, that's it. As tip, watch the video on 0.75 because it's slightly speeded up, so it will show with same speed as if you're the one playing
