I mean, I dunno what to tell you mate; they can't really fix anything based on a feel (they don't seem to have the resources to really fix anything anyway).
The special builds completely brake part of the game and I believe at least one of them has Xfactors that their build normally doesn't allow. Moonlight or Bones or whoever might explain the catchup speed.
I don't think speed really does anything after 90 - At the very least its diminishing returns.
I played once in January but essentially quit back in early December - honestly no point in continuing since the devs refuse to make QoL changes.
I'm a PS5 owner forced to play the PS4 version because my buddy refuses to upgrade - He recently moved to Toronto so our games will be too laggy anyway.
I wish you the best mate but I honestly don't know how to help
