I'm reading the suggestions on here, and if some of them are used, I'm excited to play this game again:D
I want to suggest that maybe change the looks for legendary items? Like make it awesomely obvious that someone is wearing a legend. Like for armors add something super awesome, maybe something like an aura, or a constant buff. Another idea I had was like, if you have a full legend set, it would be cool to have a constant spell buff. IE; Thieves and Archers would have like a constant enchant weapon( if they have the full legend set), and once you have that you can't benefit from the spell.
Also you should add a lvl 100 shining weapon, because the ones you can buy from the store are stupid since they need like d3 stats, and it's just ridiculous to get it at d1.
Another idea was that in dungeons, make the drop of extreme stones lower, so maybe 3 extreme stones from the whole dungeon. Also make the drop of a legendary item exact. I've been through mazes and dungeons where they have 4-5 legends drop, and some where none have dropped. I thought maybe make sure 1 drops EVERY dungeon. but only 1, no more, then the value of legendary items goes up.
I also thought maybe add some cool new unique items, like lets say +5 int, and 10 wizard dmg. A whole ring like that, something cool and new.
Maybe add some extra advantages to being a guild master or a certain rank in a guild? Maybe a guild leader should be able to have a separate message, like merchants have. Another thing to that is, that during like snow wars, nation wars or castle wars, the guild leaders should be able to get some advantage, maybe like a +g4 effect side symbol(just an idea) but only during the duration of the war, on only on that map so people wouldn't be able to use it outside, that would also encourage people to actually join those wars. Another thing for the wars is, you should actually make the secret areas work, like have cool things drop there, maybe not much, but something at least.
Then, I agree on the staves topic. You should somehow encourage people to wear staffs, or maybe even deny priests and wizards to use shields. It would really make the game cooler, thus seeing new rares being used and stuff like that. Maybe even add a rare for staves only like chance of spell cast on hit. And make it actually useful. Right now the shinging weapons get no actual bonus from the spells. You should add a cool thing like a rare only on staffs, Horn of iceberg chance on hit. That would really even out the speed problem that might come.
Also one question arose when writing this, are you going to remove bugs like ice death and double ex? I think you shouldn't, because they make the game interesting. Someone has even said that they are not bugs, they are meant to be in the game, I don't know, maybe you should clear that up?
