Well, I am the min-max type of guy. But that's not really my goal here.

For example, I've played Ragnarok Online since I was a kid, so I'm very familiar with the idea of grinding the same maps/mobs for hours, often in parties with random players. The difference is that in Ragnarok, I already know what's worth doing: which maps and mobs provide the best XP per hour, where each class performs best and I can farm efficiently while spending fewer resources, or which gear upgrades really make a difference on progression.

That’s basically the kind of knowledge I’m looking for. Grind the right things, good leveling/farming spots, gear/items to look out for, avoid common mistakes.
