I’ve been playing advanced only since you made matchmaking available for it (Thanks btw!). While overall the damage of the mobs and bullet sponginess reminds me of UVHM most of the mobs are managable usually (especially as a ranged when you can take cover).
But one of them started to stand out for me. The most trouble and wipes usually comes from Thrall Brutes. The problem with them is they spawn way more numbers than their damage and survivability would suggest in Advanced. Often they spawn in a group of 3 WITH additional trashmobs or even a large mob like Bonecrusher (which is hilariously easier to handle than a single Brute).
They have a medium health pool but their shield can mitigate a huge amount of damage. Yes they are vulnerable to headshots but most of the time you can’t take your time aiming because their gun damage especially since they like to spawn in groups can shred you in seconds. Not only that but they have a grenade launch ability which can almost one shot you. Granted you have an aoe indicator for that but on the other hand it’s pretty large and sometimes hard to see with the other effects around.
Even in Rendain various phases these Thralls are the most common causes of wipes in my experience. Espeically when Warlord Nix and Rendain in his last phase summons like 10 of them around the map. It’s like a death by firing squad if you can’t start thinning their numbers in seconds after they spawn you are screwed.
I am not sure if anyone else feels this way but if it’s not only me then i would suggest looking at their damage numbers OR increase their ranking in the mob type so they don’t spawn in hordes in exchange you can buff them a bit to be a solo elite mob type.
