I know how to play. It bothers me to play like a jerk, but I’m trying to get the titles and need to earn those medals. Those triumphs promote bad gameplay like crazy. While doing the collector one I would just leave games after the primeval came out. Doing pretty much the same thing now working on the massacre medals for reaper which I am somehow still 0/10 for despite wiping entire waves solo in the blink of an eye.
The thing that I find funny is if a prime engram drops and you're on the final match for the powerful engram ... it's totally optimal to leave the -blam!-ing game right there and then. Same situation in other content if a prime engram drops. Horrific design.
