Ilvl sync and no morale is what irritates me tbh, they have 3 options, leave it as it is and let them be casual about the whole experience and piss off their advent pvp players for those that still exist.
Second- create a progression filled frontline with morale implemented and no ilvl sync. 1 for casuals 1 for those who want to participate in progression pvp. If it doesn't work.. take it out w.e; use it as a trial run.
Lastly restrict the lowest minimum gearset to i90, and highest to 100 pvp. give the noobs i90 pvp gear as a default set.

work is done.
