Do you think Chewie will “require” Bossk, Embo, Aurra, or Jango?

I'm sure Bossk will make it much easier, but my guess is that any decently geared and modded BH squad will be able to clear it. I don't really understand all the speculation that the difficulty will be through the roof - it wouldn't be consistent with the legendaries we already have. Even Thrawn, who is widely considered to be the hardest one we have now, can be done pretty reliably with a G8 team with okay mods.
