The biggest change I want to see is higher knock-back damage and a return of Sleepywood's original size. Why not make Sleepywood a party play area for lower levels instead of constantly adding new content for them such as the Fairy Academy, Rienna Strait, or Golden Beach. Just make it simple and give back what Maplers long for

I'm all for Hene Hunting Ground, i mean it's not like it was hurting anyone, it was awesome... and make hene look like it used to please, i don't like this new look, its just....weird...

hene hunting ground pls?

Slime Tree.
Honestly, I have no idea what was going through their heads when they removed it. It's not like those maps were obstructing travel or anything.

EDIT:
Even more of a long shot, since so many quests rely on this, but the original locations of monsters. For example, Evil Eyes only appearing deep in the ant tunnel, Curse Eyes only appearing in the Sleepywood Forest, Copper Drakes and Fire Drakes only appearing in Perion (their original storyline was that they got "banished" by the other Drakes from the caves because of their weakness, and some of them eventually adapted to Perion's heat to become Fire Drakes), Bubblings only appearing in the Subway station, etc.

Seeing Evil Eyes in Ellinia and Fire Drakes in the freezing-ass tunnels in Sleepywood annoyed me right after Big Bang, and still annoys me today. I mean, if you insist on changing up these locations for no reason, at least throw in a hue slider or something to get their colour schemes right.

pre big bang?

Db/Cannoneer Revamp.
