Some of my opinions as a veteran
Going to go ahead and address the Elephant. I'm a Gyre main because she is essentially aura damage, and pumped as high as it will go, you can truly speed through content faster than most frames since her roll is like a tele-dash, and just flattens enemies as you flow on by. And I love electric/lightning kits. I'm not inbred enough to still claim Loki master race still, but he's incredibly slept on, he still trivializes majority of content. Grendel defenders will be blocked, go play a good chunky frame like Atlas or Rhino. I think Banshee should've been reworked 6 years ago and deserves next rework before Equinox. Best kit was tough. Jade is AC130 frame to me, does Hildryn loop but better, but less damage obviously. Caster category is not super clear, Dante also really stands out there. Sorry this was all over the place, I'm just riffing and it's impossibly late
