Call of Duty overall has been disappointing the past few years and campaign isn't the only example of this either. Honestly, I haven't been excited for this series in a long time and even when I give their games a try with an open mind, I feel disappointed every time ever since the Black Ops 2...
I agree, WW2 was sloppy garbage that was dead before the 1st DLC. Anyways, i'm not very excited yet because I really don't want a future based game. I hope they bring back the characters from previous Black Ops and can create a supply drop system(let's be honest they're 100% going to have supply...
It's not very noticeable. Red dot isn't worth the slot imo, the iron sights are fine. Extended mags and steady aim are good choices. Rapid fire isn't very significant from what i've seen. Personally, i've felt a substantial difference between grip and no grip with the BAR.
