Done now. Forgot I already posted here or I would've edited.*
Like other people have said, overall I didn't find the campaign that difficult. The only thing annoying was the missions where you had to breach multiple houses and until you were done you didn't get a checkpoint and your teammates won't help you. The second floor almost always got me killed in each building unless it was small.
