I mean I disliked it for the same reason that a ton of other people hated it lol. Like a majority of the community hated it and still remember it as one of the worst things in a cod game. And for myself I liked MW3 specialist a ton in terms of killstreaks because you get the specialist bonus for all perks and proficiencies minus the two attachments one but you just run two attachments from the start. Then you go for the 30 kill MOAB which I think is awesome. I loved BO2 because of the point streaks rather than kill streaks. You can earn more points for capping an obj and killing someone. It encouraged running around and gunning more.
But I understand the powertrip MW2 streaks gave. For me it was always just get the harrier, get the ac130 and then get the nuke or get the predator into the harrier into the ac-130.
