What key do you prefer to use, NOT what is most commonly needed to open door (supposedly RNG so 25% for each anyways) and what key you use the least? I usualy run Decaying since my inaros has no shields to be penalized but I solo it. This is just for me to see how hard it is for pubs to have each key for one squad in general. Sometimes I can't find 3 others who all have different keys in standard pubs and when I recruit peopled only play 3 or 4 games before they depart and recruiting takes a while sometimes so it not worth it. I'm famring ciphers for mirage and corrupted mods but soloing is becoming a pain.
tl;dr So just tell me what key you prefer to run with and what key you avoid to use at all costs.
I usually use something like Inaros or Valkyr with decaying as well, or else Hobbled with Volt's speed boost and liberal use of bullet jumping to somewhat negate the annoyance. When I join a group though I'll generally fill whatever key is needed.
Hobbled is obnoxious - that's always my last choice, if I get to pick. Extinguished is annoying, but not like hobbled, where I feel like my frame is broken or something. (Just had a Riven challenge with a hobbled key equipped, and it's like a slow-motion horror movie sometimes . . . )
I generally use hobbled, but it's been quite a while since I bothered with keys and going for the vault, and when I did it was with a rush equipped Ash Prime, so it didn't really affect much. Plus it's not much of an issue to go slightly slower in my opinion, and I mostly use bullet jumps and slides when moving all the time as is, which reduces the annoyance.....
I run Extinguished, both solo and in groups. Saryn prime with a heavily modded Sobek with acid shells is enough to oneshot basically anything, and the viral proc + corrosive explosion wipes out everything nearby even with -50% damage.
