I've had this sentiment expressed to me by more than one raider for whom the endgame was the be all, end all. The top guilds on my server in BC and Wrath disappeared within weeks of the new expansion dropping. I watched one of the top rated guilds pack up; lock, pally, bank and gnomes; and beat it to another server, but not before lambasting the lack of quality players. It was dead within three months. The few players I knew from that guild, great people I had lots of fun running with, have disappeared.

Our wants and desires and needs in a game such as this changes as we progress with our lives outside of the computer. It took my officers and I some months to process that some people we cared very much about have decided this game is no longer for them. We won't see their names log on anymore. They have been replaced by new people, no less skilled, no less exciting, no less friendly, just wearing a different name plate than the one we used to see.

I think this paragraph is key to your post. "I've loved my time in the game. I'm happy with all the people I've met through it. I'll keep playing WoW because it's fun, but I'm no longer a hardcore player. And all the friends I've made, well, I'll talk to them on Facebook, or text them. Or hang out with them in person. If I take anything away from WoW when I stop playing it will be all the friends that have come from it." The game you played before filled a niche at a time that you needed it. You've made friends, moved beyond the computer, and find that a "game" no longer meets what you want out of life. You're playing, not out of an obligation because you're a healer, but because it's fun.

Don't apologize for where your guild finds itself and your contribution to that. Maybe your guild needs to decide what it wants to be and maybe that isn't a raiding guild. Maybe just a place for people to hang out and run dailies is all that it is. That's a good place to be, too.

The game, as it has been designed, has always accommodated various play styles. Hardcore, world firsts to "I just want to fish off the dock in Menethil" have found people to do that with. You'll be fine however you choose to play or, when that time comes, you choose not to play.
