Occam just one thing in bo2 everything countered towards streak bonus not just caps and kills, in Dom in ghosts only the first person on the flag gets the add which is shit, I loved Dom but very rarely play it in ghosts.
The challenges are lazy, why not have all the challenges unlocked so you can do any you want instead of having to wait for them to rotate or spend some squad point you just earned on rotating them.
Three are no where near the amount of people playing ghosts as previous cods, 4000 players in kc playlist is woeful, now that might be down to some extent to being on ps4 but I believe black ops had the most players and its been in decline since, even youtubers are leaving the series, and to some extent they are to blame for how the community is.
I have many days played on ghosts, I'm almost up to unlocking my last soldier I've prestige to six or seven times and still play the game but thus is the first time I preferred the previous game, is there fun to be had, yes absolutely but its just harder to find.
