What benefit is there with no pausing anyway? It's removal doesn't really improve the game for people who already don't bother to use it.
If you have to ask, then the point is lost.
Don't make me have to pause the game, which I view as a crutch, to do something like use squad biotics or simply shoot my own sniper rifle. In SP, if their is a pause to issue orders, etc, make it optional. Let me program a good set of tactics that my squadrons will follow without me having to stop the fight to tell someone to do something. DA2, while notcperfect, had a programmable tactic system that I like better than, "hold on, all you had guys, don't do anything until I'm ready."
It makes combat much faster and fluid. To me, more fun.
But keep the pause in SP if you want, just don't make it mandatory. And it obviously wouldn't work in a 4 player co-op MP, so keep it out of there too..
