This movement speed bug abuse just pissed the hell out of me and it needs to be fixed asap!

I've just finished a losing match with who I think are two people in a party cooperating to abuse the hotswap movement speed buff. It was an Emet and a Tech. Hank. Anyway, at the beginning of the match, the hank seemed to have dc'd and the medic hotswap'd to the support to gain the speed bug then hank connected afterwards.

I couldn't do anything. I was still 75% hp at stage 2 will all three hunters including daisy with 2 strikes, the Emet just run away faster than Usain Bolt so I couldn't really kill him and he just beacon the other pricks back in the game.

I tried baiting him and pounce to no success so what I did next was to just fire breath him in the dome after killing the support but no success either.

Since there was no hope, I just killed the trapper and hide (after beacon). I might've lost the game but I still had them sit there and wait cuz they couldn't find me. What an extremely annoying bug! Ahem... Abuse...

For anyone curious, the map is Orbital Drill (not Cataclysm but I've had it happen in Cataclysm too and I was a kraken back then so it was still manageable).
