If Bungie put the LFG tool into the game instead of just on a phone or this site it would be better. Also, optional match making would be better than nothing but it wouldn't be ideal. Most MMOs have an LFG tool in game so Destiny can use one too. But, in optional match making raids in FFXIV tons of people would just leave after one wipe; like Alexander or Dun Scaithe type raids. People with high levels of experience going for a quick clear won't stick around if there are too many noobs or wipes. Sorry, that's just how differing gaming ideologies are. When I was trying to do legendary astral one guy left even though we were successful one of the phases with five seconds left on the clock.
