The PvE items were removed due to several complaints we had from several players, you can also check few topics on forum or refers at discord.
In 99% of the arena games played the PvE items were used in the purpose of ignorance. The thing is that in general PvE items cost more conquest points than 550 ilvl gear and it is well known that everyone who already have PvE items they already have full 550 ilvl gear so instead of using, the downscaled 540 PvE items we pretty much forced players to equip the gear they should equip inside arena.
Now on topic:
Administration decided to reject this suggestion.
The reason behind this decision is that most of the times there are only 2 healers in queue, so if those 2 healers play all this games with every participant in arena, the other DPS which will be in queue will probably wait for 10-15 minutes and that will have a negative impact in how active our arenas are.
Also, 3s shuffle will not guarantee the fairness you are looking for because there will always be an inexperienced player in the game who will eventually play with you and when you (or any other else) will lose rating we will have the arguments that the 3s shuffle won't let you push rating. Right now according to the new changes we made, the 3s solo queue is considered a rated bracket because you can literally earn gold coins, titles, mounts etc.
Declined.
