MMO without grinding? Can anyone recommend me an MMO with little or no grinding?

Can anyone recommend me an MMO with little or no grinding? I remember playing an MMO called the planet side before Sony ruined it and everyone stopped playing. The great thing about this is that you can be immersed in PVP action from the very beginning and still be useful to your team, even though they were at a much higher level than you. Are any other MMOs like this? Thanks in advance!
