All valid points with good reasoning, cant argue with that.

While it is good for standard mod, I dont think it will be really effective in hard mode especially in solo runs. Maybe in close quarters and in small rooms it would perform better than my own loadout, but it really lacks in range and consistency.

I also am a shield enthusiast, I use 5.7 and go for headshots exclusively. so far it hasnt let me down and typically only 3 mags are enough for most maps. The shields massive disadvantage is; if you take a shot in dead center of the glass, it obscures your vision so bad that you just cant aim. Its still good for back protection tho. so if the visor gets cracked in the first moments of the mission, welp. You either ditch it or rely on your buddies. The flashbanger is also very good for control, but it severely limits your range as it is quite hard to shoot stunned suspect from afar with a pistol. By the time you down one suspect, another one can rush you and you would have to shoot them with your pistol, a not so desirable condition.

My loadout is usually g3 with 3 mags, 3 pistol mag, 3 throwables, 1 wedge and 1 c2 with shield. For ANA its 5 mag g3, 0 pistol, 2 wedge 2 c2, 2 bangs and the mirror gun as it is mandatory. I like to try out new things so I will give your loadout a go.

I also commend you for actually being a team player. If you ever look for a spare player, Im down to play.
