Just a few quick suggestions.
-I would imagine this has already been suggested for Dueling but an implementation of the skills CD reset thing like in the dungeons with 3.4, after a duel.
-Then also I think it'd be cool if we could do 24hr clock with our times now for the Server Info since we can have 24hr on our time stamps but as far as I know, not the info section.
-It would be nice if we had something similar to FC's board messages, for our Linkshells. Can be something that sits on top of the LS tab and can put a brief message there or even multiple tabs would do for notes and stuff but just the initial message would be nice.
-You can also still trade cancel peoples teleports as well. Not really a big deal to me since my group of friends would simply mess with each other but that's it as far as I know, not to randoms. You can trade someone at the end of their cast, during the animation before they actually leave the area.
