Wow, that was a lot and I don't have the gas to respond to it all but your well written comments about class diversity is the one I'll take. If you've noticed the second sub classes for the guardians then you'll see that the Titan (my build so I'm familiar) has the dome of light (someone correct name if not accurate) that protects all under the dome and recharges their shield for a period of time after, akin to the healer class. Most of the other guardians have different but similar traits to their next sub class. I'd presume this is to ensure longevity and protection during a 3-5 hour raid. Your points are well written and clearly thought out but perhaps A) Let the game launch and B) Do a little background work prior to saying the developers missed the mark.
