MapleStory 2.0: What else should be changed?

WEll, since no one else is commenting, I will add a new suggestion to the thread.

5 - New exp formula to the party system. Partying with other players should be faster, if not as fast, than training alone. It's just dumb that the only way to for partying to be usefull is with Holy symbol, and it is because of this that many people creates priest with the only purpose of serving as HS mules. For this, I'd like to see party given a exp bonus. Something along the lines of

- 2 ppl party = 100% exp + party exp bonus
- 3 ppl party = 110% exp + party exp bonus
- 4 ppl party = 120% exp + party exp bonus
- 5 ppl party = 130% exp + party exp bonus
- 6 ppl party = 140% exp + party exp bonus

And make these bonuses stack with HS. It is not easy to form a party of 6 people, neither fit it in all maps, so a 40% exp bonus wouldn't be broken. This would totlly guarantee the revival of training parties and would make bossing more benefical.

That's entirely redundant. What do you think the "party exp bonus" is? They could just increase the value.
