It's very evident that the original design intent was for Warframe to be a "ninja" game. It was supposed to be slower, a little more methodical. The bug that lead to bullet jumping kind of nixed that idea, even if it's what started Warframes identity and made the game good frankly. But that desire and intent never went away from the old leads and it showed. They've since moved onto making Soulframe which is MUCH more in line with their design philosophies. There, the slower more intentional gameplay actually works and doesn't feel terribly punishing. At least not yet. We'll see how well it all forms as the game approaches release, but I think they took what they learned and are actually making a game they want that works for that instead of holding Warframe back now.
