I can't speak for everyone else, but some of the requirements for onyx medals in GoW 3 are ridiculously one sided for no reason. Lancer, hmmerburst, headshot, stomper, etc. only add up if playing versus matches. What in the world was the reasoning behind this? There are tons of players like myself who don't play much versus finding horde far more enjoyable. Therefore, many of the Onyx medals elude us. There are many medals that should also be capable of being earned in Horde. I simply have no interest in playing enough versus to earn 6,000 kills with all the main weapons, nor do I have the time. Why these medals can't be earned in horde mode makes absolutely no sense. I don't know whose brilliant idea this was, but for goodness sake, if Onyx medals return in Judgement Epic should really fix this.
