world of warcraft: should i quit or not???

i have been thinking of quitting wow, since i haven't been playing in a while. i got really bored once i got both my characters to 70. i guess i mainly stopped playing because the people i played with stopped. i don't really want to quit and delete my characters though, i spent a lot of time and money getting them up to the highest level. it just feels sometimes like i have hit a plateau as i don't want to spend all of my time doing dungeons and trying to get better gear. i need to find someone to play with or give it up for good. know anyone who wants to play with me??
