It shouldn't be speeded up until otherwise the game would be "over" really fast.
For example, I think it is too fast in lower levels (until level 50). It is so quick that you almost don't explore the full map / monsters in it. I've spend like 1 hour killing moldies and Aqua.
Until the team is ready to upgrade the game (new planets, new levels) the changes I would make:
- Reduce/Limit prize moneys from quests: When I'm playing in parties nobody even bothers picking the materials because the prize moneys are so high. Most of the money should come from selling materials and not quests;
- Add rare items (1 rare weapon per map for ex) to make the "grind" of killing the hardest monsters worth it;
- Increasing leveling time but add new quests - increasing the exp points from quests;
- Add features to make relevant other places (Zant, Adventurer plains): eg: specic drops only around that area; specific NPC's that only selling a specific item there.
