Around the middle of my challenge quest, I suddenly had a big loss streak. It just seemed like the team was not doing enough despite my 50 ton Mediums pulling good numbers. After a period of analysis, I deduced that the Assault pilots in my team were not doing enough to make a difference, due to either incompetence, or cowardice.
I got off of my basic-d Mediums and jumped on to my 6xUAC5 Dakka Whale named "Piston the Cheater", and it was pretty easy to get the requirements after that. See enemy mech, shoot enemy mech, enemy mech goes pop. Even if I die I cause enough damage to the enemy team so my team gets the edge. Also had a back to back penta-kill.

For me, it seems as long as I pilot my Whale, 1 kill + 1 assist + win challenge is nothing hard. The challenge had attracted so many underhivers, that my Whale had very little problem dakka-ing them to oblivion. Did run out of ammo on couple of occasions though.
And apparently now I am richer than Blake.
