that's just the beginning. wait until you get 3 of them on your team. LOL pc users have been screaming about it for a looonnngggg time and it's still an issue due to the way certain quests for items require 'x' number of gambit or crucible matches. they really need to look into adding alternate yet maybe longer paths to acquire said items without going into pvp/matchmaking events so the afk'ers don't negatively affect gameplay. or maybe, instead of just x number of matches, you have to participate in said matches by getting a certain number of kills or something for it to progress.
I've experienced it on PC before. (have the free version from November last year) It's why I bought it on XBOX instead of just getting the additional content on PC. Went into rumble and it was only me and another guy active. Never even saw the other non AFK guy as he just farmed the AFK guys on their spawn working on his mountaintop.
i invaded one match where the other team had 3 afk'ers. i farmed them repeatedly for solstice set. LOL
the one guy actually trying stopped and waved at me once as i was on my way back to the spawn point. :D
