It is irksome. There are poor choices to the extent that I have to wonder what the multiplayer designers were thinking.
Claymores have been an issue in the series - multiple games in the franchise have tried to address their balance, some have omitted them entirely. So you would think, in designing a new Call of Duty, it would be a known trouble area. Yet in the game you can have two of them, you can put them behind doors, you can have them replenish, they explode without a chance to move away.
As you highlighted there's pointstreaks. In Modern Warfare 3 it was identified that the killstreak system didn't encourage team behaviour. That has been expanded on in all of the Call of Duty games since. In this game you have to use a perk slot to be rewarded for playing the objective. Why?
It's really bizzare. There's 12 years of these games to look at, within the franchise and outside of it, and there are glaring mistakes that you think would get caught at the concept stage.
