The section headers for your Arsenal/vendor lists are too hard to read (Helmets, Armors, Weapons, Minerals, Materials etc. which appear with orange or blue background), except the section you have selected currently. Make the text brighter or the backgrounds brighter so that the text stands out more. (This would make the list style view much much much easier to work with)

The chat box in the lower left that lists messages sent between players as well as what loot was picked up (Has an up, down and bottom scroll buttons to the left of it). The text for items you pick up is too dark and incredibly hard to read, add some kind of backdrop behind the text (Like what WoW does) or make that text brighter.

Private messages are displayed in purple/pink font, why are there " " tags around the message? It is clear enough that it is a personal message so the " " tags just clutter it up for no reason.

Lastly, all text in the game is too small, can we have scalable text/UI? I found WoW's too small by default too but they have the option to enlarge the interface/text which is great.
