So what change to maplestory rustled your jimmies the most?

I still think that there should be some kind of UNTRADEABLE rewards for players, and get rewarded more the more people join. A new system to level up stats aside from the standard ones. Something that can't be farmed with just mules or at least making that as efficient as mules.

Something like skills that level up the more you perform a certain activity. Like a skill linked to Zakum, another to Horntail, or another to particular PQs. And the more people, the better exp (up to the 6 per party max). That's the ONLY way I see people socializing again.

Removing Lionheart Castle was annoying. It was the new "PQ era" for me. Back in the day I made friends in Ludi PQ, Kerning PQ, etc. Then as the community aspect was dying out, we got LHC. The game seemed social again. Sure there were hackers and exploiters, but that's an issue with the game, not the content.

Another pet peeve is EVERY BOSS CAN BE KILLED SOLO. And what's even worse, is people aspire to solo every boss. People don't aspire to raid together anymore, or create large groups to take down hard bosses. And in this same vein, I hate that statistics other than damage are almost pointless. Health doesn't matter anymore. Bosses do % health damage. There's skills that can't miss. So on so forth. It's stupid. This game could've continued to be so good. The new content in MapleStory is amazing if they pulled it off correctly... But they didn't!

This mainly removing it at stronghold also just killed it more.

Seens that nobody talked about the Marvel Machine , making a item too hard to get or impossible in the game, and only able to get where you need use money(and lucky if you don't want to use lots), not only bosses drops, but nebulites too, thinking that only now you get some nebulites from drops(neb boxes), but needing to use a cash item to fuse proer ranked nebulites(B/A).
I remember that a guy playing as marksman was hitting lower than me, but with money(and the marvel) he surpassed my damage in less than 6 months, even tought i played for years.

Fucking Unleashed was the biggest rustle I've ever had.

As a lot of people said, Unleashed was what killed it for me. The 50M damage cap, really? A big reason why I quit.
