I don't see a gameplay bugs section in bug reporting so I'm posting this here.
1. Radial blind causes enemies to enter into a Schroginger's finisher state where the prompt when you stand at their back for stealth finishers flicker constantly and you have a 50/50 chance of either getting a stealth finisher or a back finisher. This happens even if the enemy is full alert (red triangle on map). This matters for weapons that have huge differences between stealth and back finishers like hammer (12x vs 24x damage)
2. Going operator while you have any sort of buff on you with a timer (roar, xata's, wrathful advance etc.) Will cause your warframe to be left in a 90% DR state and NOT full invulnerability. This 90% DR state persists even after the buff has expired and will not allow your warframe to go full invulnerable until you hop back in your frame and go operator again without any buffs. This causes huge problems for frames like kullervo that has a short duration damage buff on wrathful advance and trying to neutralize exolizers in void cascade when you get far enough in steel path scaling, because any enemy will just one shot your stationary frame through the 90% DR as you're trying to convert the exolizer. Need to exclude short duration offensive buffs from the list of abilities that do not let you go full warframe invulnerable on operator, or at the very least give invulnerability state when the buffs expire without having to hop in hop out again.
