Hi, we are 3 new players. We used to play lineage2 years ago and decided to try it again playing one month. We want to know what are the best combo heroes for power leveling together? I think you got what im asking. Thanks for the answer!

P.S sorry for my english

If U like melee, I'd go for 1.)a Warcryer and two Damage Dealers (Dagger,Gladiator,Tyrant or Destroyer).
2.)A Warcryer, a Blade Dancer and a Damage Dealer.
3.)A Warcryer, a Tank and a Damage dealer.

Tanks aren't really needed at all once you get vamp from the WarCryer.
The WarCryer is a must for any group if you want to have a "best" combo. A Bladedancer will help tremendously too, but you could switch him with a Swordsinger if you want. You could even go both SS and BD, but then your damage might suffer a bit, since you should have a dagger or a glad.

Or if you want, you could make one Shilien Elder, and two mages. Which mages don't really matter, but a Spellhowler is very good for leveling fast.
