Students/Busy people and Nostalrius

Heya (:
Im a med student and can afford only few hours weekly to play here, was wondering if in your opinion:
1) is there any point of playinig if i could only play, say, 6-7 hours a week? (usually friday only)
2) are there any other people here like me who can HARDLY play? if so, whats your plan?
3) tips for being efficient in WoW
thanks!
