It takes time - A LOT of time.
I was freaking AWFUL at WoW for the first few years I played it but I still loved it. Six years later I still love the game and play all three Paladin specs (10k talent respec bill so far - QQ) and I'm relatively good. In my case it wasn't failure that completed my transformation from "bad" to "good"; it was my constant need to seek information and understand every NPC ability, boss mechanic, patch change, and developer decision (which also led me to MMO-Champion). A lot of people don't have that kind of drive. They simply view the game as a fun activity to do in their offtime. They're not OPPOSED to improving but they'd rather just have some casual fun every once in a while.
If you want players to get better, lead a pug through the nerfed raids. Try to offer people pointers in a very friendly and unobtrusive way. Pair your advice with a compliment - their ability to move or their DPS or another positive quality. Teach players to be better in a friendly way and they'll get better. The elitist approach ("You're so bad you don't even use Icy Touch and Plague Strike - only Outbreak! Your disease uptime is horrible! Go jump off a cliff and give your account to somebody less terrible!") will only make them hate you and further the increasingly hateful relationship between "elitists" and "pugs".
