Music instruments and Ping Latency
I’m not too sure I even care about this. I would rather the arenanet devs spend their time more fruitfully fixing bugs , adding content, and overall improving the game. I recall hearing that some bugs are going years unfixed, but I haven’t encountered any bugs! Save for one where a ascalonian ghost was in a tree shooting me with bow. The bug fixed itself. I do own the bell though, so I could see the use in having a bell respond at a faster rate. Client sided? Nope.
