I hope to God they don't fck it up, because I fear they're going to try to casually it and ruin it. Keep factions the same, add more game modes and more customization to your character. I wish you could just have a default or your own character for online. Search & Destroy in the vein of Call of Duty 1 on TLOU would be the ultimate skill based MP play.
Single player is going to be amazing, though I do fear they will ruin Factions somehow.
