Last year's Call of Duty hasn't been abandoned for Black Ops 3 yet (and most likely won't be considering they have different developers). The PC version of Advanced Warfare has been updated with 25 fixes, some buffs and nerfs to weapons and other various improvements.
After this update matchmaking should have seen an improvement as well as connectivity. The update brought fixes to some exploits in the game too: the bug that caused players to become invincible after calling in a Goliath has been fixed, map exploits in the zombies mode and out of map exploits have been adjusted.
Here are some of the game updates in more detail:
