So last night I tried doing the Crota Raid with 4 different groups... 4 fecking times they couldn't get past the bridge! Seriously, the bridge is the easiest part, yet they were all like headless chickens. From randomly leaving the Totum's, fighting over the sword once it was dropped, some of them didn't even want to pick the sword up, some of them that did wanted to kill some adds on our side of the bridge before crossing it then losing the sword.
I gave up and turned it off - I'll never get to level 32 with these hopeless fools
