Look, I hate Long Shot and think it's an absolute waste of resources, but how can anyone say that gameplay has taken "several steps back"? I didn't play Madden 17 obsessively, but to me it's clear that 18's gameplay is far superior. That's not to say that it isn't still very messed up, of course. Every back runs the same, the tackle animations are still horrible, zones are still pretty bad, etc. But when my QB got injured and my backup came in, I didn't adjust my play style and boom -- 2 straight ducks right over the heads of my receivers. Run blocking is much improved, even though pulling blockers and FB's STILL -- my dear God, S-T-I-L-L -- leave you completely hung out to dry like a cruel joke.
Some stuff has been noticeably improved, while problems that have persisted for years are still there. However disappointing that is, it's not "taking several steps back".....
In the end, Long Shot didn't screw gameplay; it screwed CFM.
