I damaged and and let a Flame Thrower kill 10 enemies, one attempt only pushing, other damaging a litte whit a sword and other only blocking, but the challenge doesnt ping.
I remember monts ago this challenge was unlocked for me doing Fortunes of War on Cataclism, but all the team died before complete the map on this attemp and I think I have this challenge bugued since this.
This is the only challenge I miss and my loved friends are bullying me for it because all of them already have it.
I play on PC
Thanks
