Totally agree, specially when it comes to chatting. It's essential to speak while playing MMORPGs, and it's very frustrating when we want to say something and then we have to click on menu, open chat, choose the channel, and only then type. It becomes worst when you want to use emoticons and you'll have to pick an emotion out of many emoticons displayed in different tabs :(
The hotkeys f1/f2/1-9 to open menus are not useful, they are as slow as clicking sometimes, and now that the game is fullscreen, we have to move our mouse long distances to pick what we want.
I understand the way the menus are displayed nowadays are perfect for cellphone playing, and I love the fact that the cellphone HUD structure is the same as the computer's. But we should rethink at least the chat menu.
