Mid-way through Wrath of the Lich King blizzard took a completely new approach to leveling. It was not only new to WoW, but as far as I know it was new to the entire MMORPG world.
This one feature allowed you to level a toon as a tank or a healer from start to finish and expect, as long as you could get decently quick queue times (and to begin with atleast, they were instant, regardless of role) that you would get XP per hour on par with questing as a DPS spec.
No longer did you feel like to, in order to avoid leveling at between 25% - 50% of the rate a DPS class/spec would level, you HAD to be DPS, but you could be learning SOMETHING about your spec as you leveled.
Previous to this most players leveled as DPS, and built a healing or tank spec at max level, then spent days or weeks pouring over theorycrafted material to learn their specs at max level where they were suddenly introduced to the entire spec all at once with no concept of synergies until they jumped in, head first, into an instance. And heaven forbid your first several instances were pug heroics picked up out of trade, since you were likely to, at best, cause the group to fail. At worst you could expect to be kicked from the group and replaced with a geared player in your role.
This is where I learned to heal. First on a druid that I had always planned to heal on, but was scared to level. I wasn't fond of either of the druid's DPS specs, and waiting in whatever leveling hub I was closest to in order to pick up a dungeon group spamming general didn't appeal to me.
Now with the introduction of dungeon finder, I was able to level the toon in the manner I wanted. I have since leveled 3 healers to atleast 85, and 2 more at on their way up. Most of them quested to 15, and only completed in-dungeons quests until getting to MOP, at which point they did the bare minimum quests, or I bought gear off the AH to get them into dungeons.
Now suddenly with this expansion at level cap, I HAVE to have a DPS off spec in order to see all the content before new content patches ship. I haven't even SEEN shadow form on this toon since level 30 when I played with it for an hour after buying dual spec.
To get back to my original point, I don't think blizzard has thought about the number of toons that were leveled strictly to be in the non-damage rolls. Most of my healing toons saw little-to-no DPS use except goofing off at end game because I was in raids where I took the gear simply to avoid DE.
I understand the approach of "For the previous two expansions players have sat in he main cities and completely ignored the wide world that we have created. We feel like our player base is missing out on so much", but we're asking for a better solution than "You have two specs, and DPS is now required to gear up at a rate similar to previous expansions."
Can we get gear strictly from dungeons and raids? Sure.
Will 5.2 be out before I get to see even raid-finder versions of the later parts of 5.1? More than likely.
If you want us to see your dailies, fine. But what about making it only required for one toon? I'm sure there are lots of non-DPS mains that have DPS alts that could be leveled. Make the tabards that are only available at exalted give dungeon rep and be account bound. Or give an account bound exalted only commendation similar to previous expansions.
Not an item that still requires us to do all the reps to unlock all the valor items, but reduces the grind time, but something we can send to our non-DPS toons that we would prefer to only play in a group, after we have gotten through the grind once on a toon. I don't think it's prefect, but I think it's alot better solution than we've heard so far.
tdlr; I understand dailies aren't going away, Blizzard wants us to see this beautiful new continent they have created, but with 5 healing toons I don't want to see it 5 times in order to get geared for end-game in less than 4 months. We need some compromise, and only requiring a rep grind on a single toon is one solution. What have you got?
