I want decent challenges like blops2 had decent connection in core, no bullshit scopes ( future stuff that doesn't bode well), do kill streaks like blood 2 support and assault in the same list, no specialist.
But unlike ghosts it needs to be fast paced and fun even playing solo.
Also make playing objectives way more rewarding than farming kills.
As for dlc I like how its done in battlefield more maps and guns and challenges to unlock those guns, as said before less reward for playtime more reward for challenging yourself.
