ME3 undo the Sniper nerf?

the infiltrator class in ME3 is nowhere near its power in ME2. sniper time dilation, fully upgraded, is barely noticeable. its takes Shepard almost 10 seconds to chamber another round. im literally just gonna delete the save and start over with another class, who at bioware just hates the sniper class so much they've essentially nerfed it into the garbage? i loved playing infiltrator in ME2, and ME1 remaster is better now that any class can use any weapon. but theres no reason to play infiltrator in ME3, unless you like the handicap. bioware please up the time slow effect to like 90% and increase Shepards reload speed with sniper rifles. Shepard chambers the next round like they cant find it, does not move with a sense of urgency befitting combat.
