I didnt start boxing till about 100, really. The content is there and you have to want to explore it. Yeah, you can just have three mages and three merc healers and beat the living shit out of everything... at that point you might as well play another game.
I started out as a necro and put in the time while I had it. Figuring out what I could do and couldnt, as a necro you can go from 1-100 max aa and do most everything with some time. Add in a mage and shit just gets easy, druid, bard, sham, whatever.
I stopped playing back in 2000something when the moon appeared in Everquest, I wanted to see everything and kill every encounter that I could without help. Really comes down to having a buddy or two to kill some event that had 40 people before and you barely make it.
Same thing really happened with Lvl32bard here.. ends up getting 6 maxed out raid geared guys and hes fucking bored as shit.
I havent logged on in a week or so because ive gotten what I can out of the expansions. (They have completely fucked and raped the last xpac). I COULD log on and get a 100hp upgrade or go get some other flag or trophy but fuck it.
Go for the necro and take your time and have fun!
