The ability to have offline trade.....
Add new commands
/move
No need to open map and select the outpost where you want to go....just type
/move lionarch and your there!
/spawnlock
Will be great to add this....What does this do?It locks your spawn in example....you typed /spawnlock near a merchant in the outpost.....when you visit the outpost you spawned at that place!
/report
Online reporting is soo much easier....Anet should hire GM's to investigate the reports....random reports will get the reporter in deep shit....

Good for newbies....
/commands
show available commands
ever had an incident where the person you kick keeps inviting you?irritating?
/forbide "character name"
with this,players cannot try to join the party
/unforbid
vice versa

only 1 scroll can be used every hour and a half
