Funny enough you should mention this, I recently (like yesterday) have went back to lineage II after getting bored with WoW.

The games grind has really been improved. The Vitality system is nice (especially you start with it full, giving you a great boost in leveling @ low levels) and the XP grind even then has been improved quite a lot.

They also give full newbie benifits to anyone under like level 40, including "shadow" weapons (so you don't have to use a shitty item or grind forever to get the cash for a good one) and buffs from the trainers, not to mention herb drops are real nice.
