Leveling,questing,pvp,raiding...it's all a form of grind. What's important is that you enjoy your time spent playing and don't worry about it.
Well, that's probably the main question about grinding. Is there a grind that you enjoy that is available to you? Solo questing is definitely a grind in WoW and WoW-like games. Some people like that, others hate it. Personally I burn out on any given grind if I do it too much, so I'm really happy that Rift has a variety of different grinds.
