Your 3rd point is just an argument in bad faith. They only just arrived 2 chapters ago lol, and Oda hasnt focused on them yet. Maybe actually wait?
Oda built up the Tobi Roppo as combatants before the start of the major arc fights. That he didn't for the VAs, is a mark against them IMO.
Your second to last point is just straight up wrong. Luffy fought Crocodile first, then lost. Luffy started fighting Lucci before Sanji and Zoro even started their 1v1s. He fought Moria before literally every other fight started before Moria ran away. He technically started fighting Doflamingo in the castle first, then Law/Luffy started their fight while everyone was fighting as well. Fighting Kaido started waaaaay before other fights too lol.
Your second point is based on the sole fact that nobody save for Kizaru can enter the dome lol, so thats a bad argument.
If the VAs were relevant, Lucci could have said that even if they made it out of the island, there were 9 Navy HQ Vice Admirals waiting for them in the ocean. They couldn't have made it out alive.
That would have been a way to hype up the VAs.
