The lack of trash has been around for all endgame raiding.
t1: Had lots of trash, but 90% of parties just had a tank pull and die so they could be skipped.
t2: No trash.
t3: Trampolines. That is all.
t4: Similar to A2S. No trash pulls, but trash for a "boss"
t5: No trash.
t6: 2 trash pulls.
t7: Annoying trash pulls pugs complained about.
t8: Minor trash, skip rest if you know how to not push doors too early.
t9: No trash.
t10: Skipable trash.
t11: See t7.
t12: No trash.
t13: No trash.
Now we have Alexander.
A1: Faust
A1S: Faust.
A2: See t7 and t11. "Trash" for boss as well.
A2S: "Trash" for boss.
A3: As a healer, I hate this trash the most. Freaken poisons on everyone. >:c
A3S: No trash.
A4: No trash.
A4S: No trash.
Savage "trash" (basically Faust) does not save your progress the way Coil did. If you left A1S without clearing, you have to fight Faust again, meaning any trash in the other turns would have been more annoying than anything if they existed. I'm glad Savage doesn't have extra trash. You're doing Savage to fight harder bosses and get 210 gear, not deal with Goblins that hit harder for no reason.
