You have to remember that all of the PvE items will be down-scaled to 496 Ilvl, increasing by one Ilvl per week up to a maximum of 512. So to take for example the PvE trinkets that decrease the duration of six of your major cooldowns; while the number may be reasonably high at first glance, in PvP the decrease is only around 20%. The same goes for the other trinkets which have special procs, all of them have their effects greatly reduced in a PvP instance and as such their effect will not be as major as you may think.

We'll be sure to continue monitoring the state of PvE items in PvP. If we find that a certain item is affecting gameplay in a major way, we’ll
make adjustments as we deem them necessary.

PvE items are scaled down to 496 ilevel and PvP to 512 so doubt that PvE trinkets will be better

This is actually incorrect, PvP items have no cap in patch 5.4. This means that Conquest gear will keep its 522 Ilvl stats but PvE items on
the other hand will be lowered to a 496 Ilvl cap. Every week after the new season commences, that cap will increase by 1 to a maximum of 512 which it will stay at for the rest of the season.


So you're correct that PvP gear will have a higher Ilvl in instanced PvP, but the information you provided was incorrect. I hope that this
clears up any misunderstandings and explains how the Ilvl ceiling works in patch 5.4.
