World Chat = No world calls. I don't even see why they're needed.
Trade Chat = For any form of transactions.
LFP Chat (Looking for Party chat) = Used for formulating parties and other sorts of things.
World Calls= If it really is a problem, just use them like broadcasts in Grand Fantasia.
This pretty much covers all public chats. Private chats are just fine the way they are.
This provides a much more organized chat, as well as in-game control. GS-Wise.
I played GF before, sure its a nice system but i wouldnt want to have it back because it is limited.
Almost all the chats here go server wide, in gf alot of the chats were channel specific, except broadcasts as far as i remember. here in EE its server wide, meaning its easy to find a party without having to go to ch1 to find one for a dungeon, you can just look in your peer and see if there is a party for the dungeon you wanted to go, or start one.
Peer is used for chatting, selling specific lvl items, finding more members or a party. and at the higher lvls its active and not bad (sure there are trolls but you find out who those are soon enough), so why change something that is working at most lvls?
If you dont like it use the keyhole on the chat to turn it off, and if you are concerned about kids let their parents monitor the things they play better (smart one turns stuff off in games).
