Scouts got nerfed which hurt advent the most(I still support a scout nerf despite that being an advent strength)
At this risk of beating that dead horse again, I always held that the TEC/Vasari scouts were fine and what the Advent scout needed was a nerf to its hull/shield/armor, which are still out of line even today.
Most scouts had to tread carefully around fighters and flaks due to their fragility, but the Advent variety could just go charging into the middle of the fray and pick off LRM with impunity. If they could be cleaned up more easily like the other scouts, I feel they would have been fine.
Fact is that we need an early-game LRF counter, and the scout fulfilled that role quite well. To be honest, I think we either have to look at buffing the carrier cruiser (fighters in particular) or the scout. One or the other (or both) need to be viable in the early-game to provide us some alternative to the LRF backbone.
The vasari scout(4 on the info card) now has twice the dps of the advent(2). The vasari scout was nerfed less than the rest which could be called a relative buff
This is untrue; the info-card is rounding off the DPS to the nearest integer.
The Advent scout used to deal 3 DPS, now it deals 2.4
The TEC scout used to deal 3 DPS as well, now it deals 2.55
The Vasari scout used to deal 4 DPS, now it deals 3.4
Relatively speaking, the Advent scout took a bigger hit than the TEC or Vasari variety. Overall, though, they were all knocked down far enough to become non-viable combat units in most cases.
This is just a few things I think of off the top of my head without scrutinizing the old patch notes.
While we're on the topic of patch notes, it's worth mentioning that the Enforcer got an undocumented buff in 1.19 as well.
Not to mention the SB is terribly hard to kill anyways even with overseers and skirantra healing the damn thing
To be fair, only very high level Skirantras have enough antimatter to juggle both scramble and repair cloud.
