While I do like the concept, a FD version of ****ing Battlefield is taking it too far. It's like he thinks that platforms are some sort of hazard.
While I do agree that he handled it in the best possible way for now, saying that FD is completely fair is flat out wrong. Truth is, some characters just dominate with no platforms around, as seen in both Brawl and Melee. That's why FD isn't the only legal stage out there, and while it is considered a starter, most people view it as a counterpick and often ban it.
Also, saying that platforms offer benefits in the same way slopes and scrolling stages do is a stretch. I do concede that it is true in some cases, but they do not help the cast nearly as much as platforms do. Platforms add so many options to help people get around projectiles, encourage more vertical combos, help fastfallers escape chain grabs and offer a potential mixup for recovery. That's why adding a stage like Battlefield or a neutral Pokemon Stadium would be a good idea.
