I just got my swiss friends to play in Mysidia, and what we basically do is Leves and Exploration. Exploration takes way more time, and when we do it, we always have a really good time!
Honestly, SPs is not our main concern. We just want to have fun doing quests, leves and explore, but when we want SPs we just do some leves and kill some monsters.
Can't wait to get them to 25-30 so we can do that awesome dungeon!
