Pvp gear question

How does the current system work? I currently have some old honor and conquest gear, but the current honor gear is very low ilvl… it’s lower than last seasons conquest gear?

Also why cannot i not queue for solo shuffle?

upgraded gear counts in pvp now? i thought upgrade was only for pve?

Honor gear is low level, but pops to higher level in BGs and Arenas.
The upgrades only upgrade its PVE stats.
Can’t answer the solo shuffle question.
