not sure i particularly like rating barring gear as it will make the barrier to entry in pvp go up compared to expansions like mop/wod where there was a lot of pvp participation.
that being said heroic ilvl loot for being 1600 (challenger) is extremely doable. my question is does pvp gear still have an rng drop change at all from matches like in legion/bfa or does it only come from purchases at the vendors?
