Well, this changes nothing. If I had to bet, they probably won't even hire a new dedi pvp designer. You guys need to face the fact that this game will never ever improve, even marginally, from a balance/design/mechanics perspective. It's all downhill since mop came out.
Although you guys putting blame on Holinka and GC are missing the full picture too. Like someone said, GC was working within way more constraints but because he understood the game and meta concepts to a decent enough degree we didn't have too much bullshit until mop. It's a matter of the devs not understanding what they're doing with the overarching systems design when it comes to pvp. When mop came, they added how many new spells, hundreds? And moved more toward making powerful 2/3/5 min. CDs. The game because mostly about trading CDs efficiently, not neutral game plays.
Used to be that people would actually die when you were just pveing and nobody had CDs popped which made positioning and things like kicks/deathing/grounding/etc etc etc way more impactful. Mana mattered and dispels/trashbuffs mattered. Everyone knew what abilities people had and which spec you were playing and it put everyone on an even playing field which was way easier to balance, it's not interesting trying to find out or predict which of 3 talents the enemy has, especially when 90% of the time it's obvious if you have sufficient game knowledge of every class like any good player should. So in that sense mop talent design was probably the biggest atrocity to happen since 9/11. Mop design is what killed the pvp in this game. Even if s14/15 weren't that bad compared to wod/legion you guys are probably forgetting how frustrating it was watching the game die back then, now we've mostly accepted it.
And for the record season 10 was the best, most balanced pvp era this game ever had with 7/8/11 not far behind
