Yeah, the Scorn are the worst for a variety of reasons. Pre-Witch Queen you could finisher a Scorn when they went immune in their scurry-run they do, but for whatever reason they removed/fixed that feature. The scorn with those shields that somehow reflect EVERYTHING are awful. I don't know why barrier shots don't go through those like when they updated the Taken Centurions shields to also be shot through with barrier. Scorn immune tethers also suck because they get spammed with little to no cooldown or limit. Screebs, though not as annoying as Fallen Exploder Shanks, (Which feel like no matter how far away from the blast you are it feels like you always take 100% of the explosions damage if you are at all anywhere inside of the blast), they are still fairly fast and can really ruin your day if they sneak up on you. Certain Scorn bosses also tend to teleport spam when tickled with the slightest unit of damage is applied. Mini screens... Those things can rot in hell. If you've ever played Hallowed Lair GM then you KNOW. The Scorn overall are extremely aggressive and don't have self-preservation like most enemy factions do, so they are almost always in your face... Scorn Censors (The stasis ones) are awful and sometimes hit and freeze you despite being off the ground. They suck. Their projectiles they shoot count as physical objects and can cause detonations of whiffs of your grenades or supers, which can lead to death... There are probably more reasons as to why they are just the worst, but I'm failing to remember anymore atm.
