Okay, so since I can only get on the game by using the computer app I have been using it just about every day and noticed some problems well, not so much problems but forgotten features.

Rift mobile: While you can chat with your friends, use the loot thing and chat with your guild, we are unable to post on the wall which, would be a good feature for leaders and other members for various reasons.

A in game feature that is widely popular is the ability to privately speak to someone which is forsaken on this app but, it can just as useful for people using the mobile app as it is for fully logged in.

Rift Soul Tree Builder: This is a nice app but, only the root abilities tell you what it does which makes it a useless app if you have no idea what the branches of a soul tree does so, that would allow players to more accurately build there soul trees.
