Capcom's pumping $600k into the Capcom Pro Tour, & that's not counting what the CPT 2017 Premier Pack will contribute to the Capcom Cup prize pool (for reference, the C
PT DLC contributed $90k to the Capcom Cup last year). Of course, if the stuff you can't say pertains to NRS's answer to the Capcom Pro Tour, that'd be a completely different story. But as fun as Injustice 2 looks, there's just too many other fighting games that typically fare better in the FGC (SFV being at the top with the Smash games not being far behind, plus the upcoming games like MvCI & Tekken 7's console release).
That isn't to say that NRS games are bad gameplay-wise by any means, it's just that they don't seem to hold competitive attention for as long as the others for whatever reason (correct me if I'm wrong, but Injustice 2 doesn't even have a Sunday slot this year at EVO).
