Will you quit if this game becomes raid-centric?

I'd rather have dungeons and temples and crap that can be mostly explored solo, but require a party to explore the deeper, dangerous, and more atmospherically rewarding sections leading to treasure and secrets.

But don't take away the instanced dungeons. They're also useful for quick fun runs which are always a plus for the MMO player with an active lifestyle. I'm just looking for something with a little more depth and room for exploration.
