While I do not play either on PEQ nor the Test server (I can not seem to find it?) I have noticed a few things on the server I do play on. I hope I am doing the right thing posting them here, otherwise just ignore this post!
1. Going to third person camera and then to first person will make the particles from both primary and secondary slot items show on your screen. This is surprisingly annoying.
2. There are no sounds while casting spells. There are sounds when they are landing though.
3. Maps do not seem to work correctly. I have not been able to pin-point this exactly, but in some zones the map is not displayed. My map for Nedaria's Landing refuses to show itself, for example. This map I downloaded and is not the original map (if there even was one).
4. Charms (ie, Intricate wooden figurine) is empty, as is the Adventurer's stone.
5. Checking out charm slot stats can make you go LD. It does not happen every time, but frequently enough for it to be some sort of pattern.
