Select difficulty...?

The problem there is in Maple everyone's gameplay intersects with everyone elses.

You can't give a mob 10 hp for one person and 10,000 for another and have them both fight it at the same time.

This, I agree whole-heartedly. Because of how Maple Story is set up, all players who plays in the same server has to interact, so you really can't set up difficulty like that. However, I'm wondering why they're setting difficulties for bosses then? Doesn't that strike you as odd? In gMS, sure, we take down HT and CWKPQ bosses in less than a week after figuring out a strategy for it, vs other servers.

My question being, with difficulty implemented, will the current bosses be harder or easier? Because at the way the current bosses are at now, are they setting that as 'normal', 'hard', or what?

The best you could do is give "easy" players a massive damage boost over "hard" players and that would severely jack up the only way Mapler's have to judge themselves compared to other players.

If "easy" players got drops more easily, or mesos more easily, or had cheaper prices, or any other advantages to make them easier, they'd quickly become farming accounts for "hard" players. taken to the other extreme, if the only way to get any of the really good things were on hard mode, "easy" players would miss out on so much content they'd never be satisfied. "No zhelm for you, you're an easy player."

Difficulty settings just do not translate well into an MMO with a shared reality unless you start segregating people into difficulty level setting based servers or similar where the modes can't mix.

It works on bosses because everyone who enters has to agree on it and is conformed to the same rules. For general game play though, it just fails.

This, I have no reply to, since you pretty much discussed everything I was about to ask you anyways. I'd like to see their difficulty-system and see how they're going to alter the bosses regarding their drops, stats, and time-limit.
