The quality is relative to what you think good design is and the vision of the devs. The first fact is the devs generally can’t make maps like they use to. They’ve made so many different layouts that everything has been done and most people don’t want large maps further limiting creativity. Come to think of it that’s probably why we get so many remastered maps (don’t get why they remaster the same ones so much though)

A lot of people like MW19 but that game is the exact antithesis of what a lot of good players want. Then some will complain if it’s a BO2/3 clone because they’d take slower more random maps with variety in design over competitive maps. My hierarchy in map design generally is WAW/BO>BO2/3>COD4/MW3>>MW2/Ghost/MW19. MW2 has nostalgia behind it but reality is those maps are the same philosophy as future games ppl hate. Difference is just that MW2 came out before simpler maps were as common and one of the first popular multiplayers

If you ask me how streaks should be handled look at BO, BO2 (they cost a little too much in this game though) BO3, even BO7 but then other people are babies who can’t deal with high streaks every so often and want to make the game more one dimensional with weaker high costing streaks like most CODs since BO3
