That's actually part of what I dig about Warframe. People can really lean into different build strategies and have them all be effective, making lots of room for personal fun. Sure, every now and then build approaches butt heads (like poor Nidus trying to get stacks when everyone else is making all the mobs dead) but there are also tons of odd synergies that crop up and as long as everyone's alive and the mobs are dead then it's pretty harmless to carry a Tenno or two with less optimized builds.
I'll admit I also haven't gotten as much out of sprint speed. I spent the longest time as an Atlas main (Before Primed Sure Footed let other frames stand toe-to-toe with beefy mobs without getting knocked down) and never actually RAN anywhere. it was either bullet jumping or using a lot of attack speed with my stance to move (I was practically a Clashing Forest main before Melee 3.0), and despite Atlas being 'slow' I didn't end up falling behind because bullet jumping is very, very fast.
One weird thing to add...I don't know about you guys but thanks to Lich Hunting I'm absolutely SWIMMING in Tenno Specters (Especially Vapor and Phase). I'm already at the point where I can toss them out like Pizzas rather than treating them like a resource. Volt and Wisp specters add more speed than we can get from all the mods combined in one frame, so that's another angle if someone likes speed but needs those frame slots (or really wants to put Peculiar Bloom in there) 🙂
