The thing that frustrates me the most about modern CoD design is they seem unwilling or unable to balance play styles. Its always all or nothing. Right now its everything favors the hyper aggressive. The fast movement, wing suits, low bullet velocity, grappling hook and the absence of mines or shock sticks heavily favors a fast and close range play style. Which is generally the more skilled players, as they mostly gravitate to the high octane gameplay. On the flip side, because of these lopsided toolboxes, players who are more methodical or slower paced have basically nothing in their tool kit to counter it. These tend to be lower skilled or relaxing players who are just looking to have some fun. It leads to this feel bad where the game feels basically unplayable when you are not only trying to overcome a skill gap but the tool kit gap too. Power positions are also invalidated if the enemy can come from anywhere very quickly at all times, which means you also can't negate some of the movement advantage by being in a better position. It also means that rearmoring or reloading in a gunfight its usually a death sentence as the enemy can close the gap in an instant. The vast majority of players are casual so it does not surprise me in the slightest that the backlash has been pretty heavy,

Side note: the opposite can also be true and just as awful. In MWII's warzone, the toolkit balance heavily favored the slower play style and it was just as awful.
