Based on the new dev post it seems like there will be a massive itemization overhaul for 6.2, and updates to class attainment stats. Im mainly referring to this comment
Since Mastery is our current best throughput stat, and all Disc priests stack this the only thing this statement could mean that they will make some major changes to our stats and either make our attainment stat mastery, or completely revamp us so crit ends up being our best throughput stat.To help bolster that sense of excitement, we’ve decided to shake things up when it comes to how secondary stats appear on Raid loot in this patch. Inside Hellfire Citadel, you’ll see a wider range of high and low secondary stat values on items than you have in a long time. Alongside some tuning adjustments that should ensure your attuned stats are the right choice, this change should also make it easier for you to identify which items are good for you in a more interesting way than just “equip the highest Item Level.” Our goal is to help make Hellfire Citadel Raid items more distinct and meaningful to you, and we hope you’ll let us know how things feel once you start collecting your new gear.
Thoughts?
