Regarding the zoomed out, i actually will feel much comfortable. But then i think the current view angle is actually quite...suitable.

I must use the word suitable because if u are building and planing strategy, then zoom out is good, but if u are micro-ing units during engagement, that is a big mess cause u barely able to click individual unit nicely. But an option to zoom out more from a mouse wheel and zoom in for current view is good. The last zooming to units and building are pure eye candy. but fun.

Chatroom 1 no need to mention already, cause blizz already promised the will be 1.
