Make a mode were you can do free roam (not a huge environment, just like map based. Goto one room, map loads, play fight blah blah next room map loads, ect ect)
Improve quests beyonhd just killing monsters, give objectives and clear conditions. Like Kill ____ goblin instead of kill 197391 goblins
Remove insta.

Anime like is cool but stuff like insta just isn't needed
Improve d-style (I'm sure something'll come up ;])
Make a gunblade, make it so that it can't flip, but it can guard and shoot. Single shots maybe? It'll be a whole new world with glitching/k-style
Sniper rifles. Deff. We need sniper rifles, include a zoom feature?
Miniguns would be a nice weapon edition. No jumping/wall running, but tumbling enabled? (slow tumbles, hehehe)
Include shields into it? Put a medieval feel to it. with shields more AP or halved damage, something like that
Being able to dual weild two weapon types, like a katana and a gun or dagger and a gun
With two diff weapon types equipped, weapon 1 is main attack and alternate attack is weapon 2 <-- keeper
It'll bring in new styles and if you keep the animation similar, more styles can be made
Two handed swords, large swords, a must
improve them
make it so they can guard? But the guard animation takes longer than katanas, that'd be cool
Like many said, no premiums
Or make a premium server were premium items can only be used there
Helps the server stay alive, and makes it fair for those who can't/wont spend money
Put ads in the loading screens for paying costs, that way premium items aren't necessary
=]] I hate premies.
Ijji is doing a good job and all, but PLEASE do not ever give them the rights
it'll be just another game full of premium items and egotistical 12 year olds
=/
Well that's all I got for now. I'll probably slap more on later
