Gear Choice/Grind Spots

Im a level 21 Human Rogue, and i play with my GF and a good friend, whom are lvl 21 Cleric and Wizard. Where would be a good spot for the 3 of us to group up and grind some exp? Ive always been a loner when it comes to lvling, so i dont know the good group spots.

Also, ive been away from L2 for a while, im sure alot has changed gear wise. What is the BEST case senerio for me gear/weapon wise untill 40 so i have something to strive for.

Thanks in advance for all your help.

20 I recommend trying the Necropolis of Sacrifice. As long as your wizard friend is conscious of how much mana they are spending per mob, you should have little downtime and learn a lot about partying in C4.

Another good group spot for the three of you is around Dion and the OB barracks. The OB barracks will still be pink and red to you at 20 but by 25-30 its a perfect place for a group as the one you have suggested.
