Yep, this has been a debate for a few years now among the community. If they're going to include a campaign; they may as well make it worthwhile in my opinion. 4-6 hours of linear gameplay with scripted scenes, soulless combat and checkpoints is just becoming more pointless every year. I can understand why they want a foundation for the game but I'd rather just see them focus purely on the MP side which is what everyone buys the game for.
Everyone went barmy with Riley this time last year but I kinda took a step back, knew the campaign would be hopeless and just didn't ride the hype. Turns out the story was worse than I expected and Riley was just a novelty edition that went on to multiply and piss everyone off in multiplayer!
