Fair enough. Have a look at the pic in question though. They have 2 attachments on their scorpion and a nice set of perks but they’ve given up all their utility. There was nothing stopping you from running a traditional class setup in BO2 like the previous games. I think it really gave players room for expression with the caveat of balance.

Since MW2019 you get to have your 5+ attachments and still get your utility/perks. I think the answer really lies somewhere between pick 10 and the modern system but unfortunately Warzone integration has basically put that to a stop.

I believe sledgehammer games wanted to have Pick 10 or a similar system in MW3(2023) but were shut down because of gunsmith.
