Yes of course, but it is still just boring to have every ops in the game dropping the same loot. Some variation would be more interesting. Loot still is one of the main aspects of this kind of game and it is always much more fun to see some new and fresh items, even if they're not better, than same old pieces.
Thats what Hardmode is for.
The last boss drops some campaign on normal, theres your loot variation
