What changes made Blade Storm OP?

[Androgynous]

Out of the loop, been playing Warframe on and off. Back when abiltiies were mod cards that cost points, I remember people saying Blade Storm was one of the worst/weakest ultimates in the game. Even when the clones were added to speed up the animation, I think it was still considered a bad ability by most unless I'm remembering wrong. What other buffs were made to Blade Storm that made it into a "press 4 to win" button?

In a short answer: Primed flow and fleeting expertise

Edit: guy below me might be right too, and it has 2 clones now to clean up enemies faster, so it can be spammed more often

Actually I'm pretty sure Blade Storm didn't do finisher damage before like it does now, allowing it to bypass that infinite scaling armor.
