Is it worth it to level here with everything fully progressed?

I have been playing here on and off for about a year. I love how huge the population is. However, is it worth it to start making this my main server if everything is full progressed? Also, I hear that pallies aren't popular given that there are so many already and that they are not viable healers but, tanks (I can't really tank. Healing and DPS is my specialty) I have read that there are progression guilds that go through each raid yet, I haven't found any in game.

This has always been my fallback server after playing other servers where the population dies for one reason or another. Any info would be appreciated.

Worth, maybe server is crowded with pallies, but there tons of bad pallies, if you are above average you won't have problem to find your place, otherwise go warlock, even the worst warlock will find a spot ;D
