You can blast Legion raids easily. It's only once you get to Mythic ToS or Antorus that you start hitting roadblocks. Uldir raids are capable of being doable solo if you play your class well even, and that is the previous expansion.
Just be patient and play the game. Once you get to level 70 in a week you should be able to clear Uldir fairly easily, and start making headway into BfA raids.
I mean, do you just want the devs to flip a switch once we go into 10.0 that lowers the health of BfA and Legion bosses by 99%? Is it unreasonable that Shadowlands raids will not be soloable even with full VotI raid gear?
