Changing the combat interface and HUD was one of the main thing and was announced way before release.
Honestly, what stops you from issue orders with Q, E and C just like you do in ME2 and ME3?
For those unaware of how the HUD and tactical menu works in ME there is a tutorial. Also the keys to assign commands are editable (and easy to find) on game options.
In my opinion I think the new HUD looks awesome.

The problem is we cannot use the commands in tactical pause. Having the display I guess is optional. But the commands will not function when you're using keyboard and mouse within tactical pause, only in real time, unless you're using a controller in which can you can go in tactical pause and the squad commands work.
