Yes, the area damage % is gonna get fixed but it doesnt solve the issue that this theme is way to strong for solo leaderboard pushing and way to weak for basically anything else.
I just went in another GR 150 on the same barb just without any area damage and still managed a 10 min boss spawn on my first key as zDPS.
I created a topic about it in the PTR Feedback Forum.
Even if area damage scaling is removed from the theme we will still have a full zDPS GR150 Solo Leaderboard!
