Yep. Thats when it started with my server. Pugging was ICC. It stopped come Cata. Its why only ~4 guilds have completed t11 on my server, and only ~2 (IF that) have done all of firelands, or even cleared it on regular.
Come guild transfers, all ~7ish guilds on my server are leaving. So... For those of us who can't afford to jump ship and faction change etc etc, we're going to be left on a server that may very well be under 2000 players. lol
