Yeah, great suggestions Noite!
Also; Remove global chat, but keep zone chat in order to make more people gather up.
It's more tempting to group up with people you see char to char. Plus making players bundle up more makes this game feel a lot healther.
And; Remove the guards in the larger cities (khemi/ot/conarch). Would be superb having fights in these cities if people were "forced" to be there for the lfg chats. People who didn't want to fight could hide around int he citis or in taverns.
Trader can be instanced, pvp disabled.
