So you all are complaining because: 1) You did what you were going to do anyway, PvP. 2) It was not a waste of your time because you got kills and would have anyway, and 3) it is a free item that you get for doing pretty much nothing with little effort as you didn't change your in game routine at all.
Please do not complain if:
1) You got your kills through medal quests
2) You didn't get the kills required
3) Didn't meet the requirements to qualify.
Quit QQing its free stuff what is the big deal? You got a bunch of kills to add to your ranks and had fun why can't that be enough? Oh yeah I forgot that the socially acceptable thing to do nowadays is be greedy and rude... right.
