This thread seems made for me. Thank you for bringing it up OP and apologies up front for rambling about what has been weighing on my mind since V's release.
I'm the type of SF fan who watches tournaments, checks the internet multiple times a day for news, enjoys lore discussions about forgotten characters, collects art books and who buys the games day 1 to help keep the IP alive. I'm also the type of fan who then fires up the game to exclusively play single player content as that is what SF has been for me since the days of II, and since human competition is simply too stressful for me due to how it forces you to break down characters into hitboxes, effective combos and other things that for me take away some of the magic from these games. V I have barely touched so far despite being as interested in it as ever.
There seems to be some (Capcom driven I suspect) common misconception going around that fighting games need to be played against other people. As if every other thing you do in them only functions as training for that. For someone like me who grew up without arcades, playing SFII meant fighting the CPU in Arcade mode. Ocassionally I'd fight someone else for shits and giggles but that was more to train with characters in order to fight better against the CPU - not the other way around. For me, there was a reason that Arcade was the first menu option and not Versus in other words.
After II and its multiple SNES versions, I also played Alpha 2 on SNES along with MK and KI, played III on Dreamcast along with Marvel 1 and 2, and played many other 2D and 3D fighting games on PSX, PS2 etc. I played all of these primarily as single player experiences; rarely did I have someone else to play against and I did not really miss it. This lasted up till IV, which despite the increased online focus still was quite fully featured offline as well.
Even after trying the beta for V and being a bit surprised by the FGC focused marketing campaign I still had not considered that the beta's Arcade mode missing menu would reflect the final build of the game. The beta was a network test so how could I have guessed - going with my lifelong single player console perspective on SF that was time and time again re-affirmed by Capcom as a legit way to play up till now - that they really would not include what for me has been the way to play SF? I was even more baffled to hear them come out afterwards and say that they were surprised to hear that so many people missed such modes - how could they be surprised by this if these games for years had Arcade mode right smack at the top of their menus?! Not every SF fan is an American or Japanese fan who grew up in arcades of the 90's with their quarters ready in hand Capcom!
I think there are a lot of people like me that Capcom is currentlty not catering to, people who enjoy playing fighting games offline against the CPU because that is how they got used to them and because that is what feels like the core game to them. I'm not saying that playing against humans is not rewarding or perhaps even more valuable, but it shouldn't simply become the only real way to play imo.
For me a Ryu versus Dhalsim match is still a thing to feel childlike glee about in the sense that you get to see a Karate man who can shoot fireballs fight a stretchy Yogi who can teleport. Human competition tends to reduce this experience to hitboxes, hurtboxes, overheads, footsies, combos and tier lists and such, which to me is less interesting as it breaks down these characters with abilities and personalities into sets of effective and non-effective tools. Fighting the CPU does this less strongly for me (apart from having to cheese higher level bosses and such perhaps).
Capcom should imo not join in on this (behind-the-scenes, overly effectiveness driven) multiplayer view on the game exclusively I feel. Sure I can to a degree enjoy this way of breaking down the game by proxy when I watch tournaments but it's not how I play and enjoy these games (which is to try and make use of all the moves of a character for instance simply because I enjoy seeing them, and as such not to stick to the few most effective ones).
I can only hope SFV will get some of the things I care about otherwise I have less and less reasons to keep supporting this series for myself and for others who do enjoy high level human matches. For me, things like stages, stage transitions, single player modes, things to unlock through single player modes (preferably not like in Survival!), overall polish and some story content go a long way to make me feel invested in the long run while I play against the CPU and while I enjoy watching others play the game on a competitve level. I'll keep my fingers crossed for now.
Edit: another way to say what I mean is that I wish Capcom would not ignore the side of SF that is like old and new Doom: enjoyable single player content versus the CPU that - if designed well - provides its own kind of rewarding experience without taking away modes from those that do prefer to play against other people.
