What PvE are you dreaming about? Makarna? Or Prometun Easy Mode?
You are refering about instances from 4.8 and 6.0., which give out rewards no one is even bothering to use (cause they have it already) or sell and just throw it at the NPC. 
Only PvE I see being done is Beninerk Easy Mode, where the rewards are split across 12 people which basically only the accessories are valuable for healing boost for clerics/chanters. Some still need stuff from the first Boss in Prometun Hard Mode, which is done within some weeks if you loot the fragments via account warehouse.
Those few 2, 3 groups who can run the second and third Boss are to be considered minor exceptions, same regarding those few alliances which are actually running Beninerk Hard Mode. And those most likely only need the weapon from there, even if. 
Oh, suprise btw.
New PvE content will be Cube and Minionite instance in 7.3.

Hopefully they wont forget to patch in the cubes for the old instances at least (insert quality meme here).
I am sorry but... what? Efforts of pvp people? I love pvp personally and I would LOVE to see everyone equally geared. Do you mean PvP peoples effort is the whole concept that they gear up and consider it just a victory to get ther gear without actually using it?
My dude, when the patch came out in august 2019 people tryharded (some went full p2w aswell with luna) to finish asap their gear. Farming and buying/gathering the materials for the starlight fragments was to be considered a really expensive thing to do due to the simply missing ressources.
My point? Give the second best gear out for free like Kata gear f.e. While tier 2 pvp is still the best, they would only troll the active PvP players (which are left, KAPPA) if the next event would actually give out this specific gear. 
EDIT: Who ever was smart gathered as much kinah and all the PvE gear/accessories/weapons from the past events since autumn. If you did that, there is basically nothing left beside some manastones and then try to make an ally for the endgame stuff. How to enjoy renewed content in aion eu in 2k20.
