@d3v, geez, this is getting frustrating...To make it very simple here's an example and I'm going to throw a lot of bones towards you here:
There are
10 guys,
9 of them are casuals and
1 is a competitive or pro player. (That quota is very generous for pro players, they hardly even reach 10 % of the fighter gaming market.)
Each of those guys buys the game for full price. That makes
60$ from the pro but already
540$ dollars from the casuals. That is already a huge gap. You might agree with me on that, right?
Now lets talk about DLC. Your own graphic showed that it is right now at 40% of the total revenue. That's a big amount, yes, but not even half and certainly not the majority of all revenue. And that's just the old EA business model.
Street Fighter 5's new DLC business model will considerably lower the percentage that DLC sales will add to the overall revenue. This business model actually supports the pros the most to earn all their DLC for free because they easily can by just devotedly playing the game. The casuals however won't get that fight money so easy. To spare themselves the hassle they will have to buy stuff with real cash.
Also, where exactly do you get the idea from that all casuals buy the game and throw it in the trash afterwards? Money doesn't grow on trees for us. We value our game purchases too. There are more than enough casuals, take me and a close friend of mine for example, that usually stay with a game for years and pay for costumes and characters. My friend got every season pass in DOA5LR just so he can dress up his favorite characters. That's actually fairly typical for casuals. They are not purists like the pros and they love the additional fluff. I also bought the 70$ Steelbook Edition of the game. I wonder what version you as a pro got...
But I'm going to throw you an especially big bone and let us pretend all casual players indeed throw their game away after the first month, so they won't buy any characters or costumes, alright?

So that's
0$ additionally from them.
The pro however buys season passes for at least three consecutive years. Thats
90$ from him. As a reminder, in Street Fighter 5's business model he doesn't really need to pay cash because he can easily earn everything for free but that's me throwing you yet another bone.

Now lets combine these numbers:
That is
540$ from the casual market and
150$ from the pro market. See the still big difference? Are you honestly telling me the pro player is or should be more important to Capcom than the casuals, even though the casuals bring in more than triple the income? And that's only going with your strange preconditions that casuals buy nothing additionally and pros buy it all. In reality it would be more like
690$ from the casuals (if only half of them buy the season pass) and
60$ from the pro (who actually needs no season pass). See THAT difference?
And this very basic calculation doesn't even take into consideration what Capcom additionally earns and has to invest in casuals and pros. Because you bring it up so often, lets take your fancy tournaments into consideration as well. They cost a lot of money and who do you think pays in return for them. Just as Maximilian explains in the video at one point, it is the hundreds of thousands that sit at home and watch the streams or that make up the large crowd in the background, cheering on the pros. And regarding Maximilian: He actually makes a living from these people watching his streams and Youtube videos, he really should know his audience. And he certainly does know more than you and me. It doesn't matter if he "really isn't that big" or if you think he does "more harm than good".
