Have you ever finished leveling your character to 60, eager to join a battleground only to have your hopes and dreams washed away by the ruthless 1-shot-two-handed-warrior-windfury-build with BIS pvp gear?
Well with this suggestion- No Longer!
The concept is to create equal brackets to mirror the pve content side of things. This could be applied to both Arena and Battlegrounds but I think is more important for BGs. The idea is to create a metric (Item lvl/ pvp power) that separates the playerbase into 3 sections: Normal, Heroic, Mythic.
This change hopes to create a better player experience when gearing new alts and entering the pvp scene, while allowing BIS itemization and relative power level in those 3 brackets to be a considerable factor in gameplay. As it is now characters that would be in this systems "Normal Battleground" really don't compete with the "Mythic Battleground" characters because the difference is too large to feel like much progress can be made. As people get more gear, increase their pvp power and get the right REs their character power will increase bumping them up into the appropriate brackets. Even if you've just gone from Normal BGs -> Heroic BGs, you'll not be so far away from the BIS characters to create a hopeless situation when fighting them.
With such a change I think we can increase the player experience, create more milestones and checkmarks for characters gearing in similar ways to people gearing for the PVE side of things, and overall improve PVP in Ascension.
