In Ulduar, I raided in top 50 world ranked guild, clearing all the hard modes. For multiple reasons I stopped raiding, and took a break for a while. I've been back for some time, now in a guild with some real life friends, that's more on the casual side of raiding. I don't raid with them on their primary raids though, due to a new work schedule. An off night raid here and there, but non consistent raiding, so I spent alot of time playing around with alts. I recently leveled a hunter up to 80, and was pumped at the new gear and emblems dropping. Until, about a week after hitting 80, I had all the gear I could get for upgrades outside of raiding.
Progression is as limited as ever if you don't raid, and are a fresh 80. Now, if you're not a fresh 80, and have been 80 for some time but don't raid, then yes, these changes have provided a new upgrade path at each patch. But for a fresh 80, you can get all your gear in a week or two, then have nothing to do.
