Recently we had a guy join our fireteam for the whole raid. We one phased all the encounters. But once we got to Riven, he didnt have a clue you had to follow team members up the elevator to move on to the next section. Dude was still behind killing ads. Totally lost when we mentioned symbols and which eye to shoot. It only took 1 wipe which he caused for him to leave. The guy was on add duty and he still couldnt do that properly. It was clear this guy's "experience" was the rocket cheese. We proceeded to 5 man the Riven encounter just to prove the him wrong. 5 manned the gauntlet as well. Its definitely petty, but to leave the fireteam because we werent rocket cheesing definitely explains the stance of the LFG community. Bungie needs to patch this rocket cheese. Im tired of sifting through LFG players who say they are "experienced" and yet are totally clueless on how the riven encounter works.
