The War Within Beta Development Notes for June 25th - Major Reductions to Avoidance and Leech

wowhead.com:

Blizzard has released new development notes for The War Within Beta as of June 25th, which includes more class tuning, including several class changes and a major reduction to Avoidance and Leech effects!

• Developer’s note: In today’s build, Avoidance and Leech rating on gear gives half as much percent value as before, and we’ve reduced the amount of these stats given by most talents. Both stats, Avoidance in particular, are extremely effective against the damage non-tank players face. By the end of an expansion, the amount of Avoidance appearing on gear reduces so much damage that acquiring pieces with it can feel required to do the hardest content, particularly extremely high Mythic+ keys. By reducing the amount of value given per rating, our goal is for pieces with those stats to remain valuable, but for the gap between players with and without them to be closer.
• Reduced the percentage granted by Avoidance and Leech rating by 50%.
