This is exactly why I dropped a Shaman in WoW and went Warrior, and then Death Knight, and eventually Paladin. It helped that my Wife loved to play as a Priest, so I always had heals. Sure we had DPS drop constantly as they didn't want to handhold other DPS, but fuck'em, my qait time for instances was seconds, while there was literally an hour or two.
Everyone is a newb at some point, and most people don't have the time to dedicate to reading forums all day long (Sadly I read the wrong forums or I would be better at Destiny LOL), or treat this game like its a part time job. (Seriously, I can give stories from EVE, WoW, or DAoC about how MMO's consume you)
I have to disagree with your last statement though Dave. This game would be infinitely worse if it had a dedicated Keyboard and Chat Channel. Can you honestly imagine merging Barrens-General Chat with Xbox Live?
