This is what it is. Sadly.
I’m gonna show you some of my “best attacks” with Physical damage, I want to tell you, I’m playing normal Spirit Wolfs and Legacy of Frost Witch (Which in total increase 55% my Physical Damage). I’m full gear by the way.
Stormstrike
Windfury Attack/Doomwinds
Flameshock
White Attack
Spirit Wolfs:
Also, most of Solo Shuffle vs Meles, my top damage is Lighting Shield by far.
Even vs characters with not full gear/low armor, these Physical attacks are one of my best Attacks, overall i can say my MAX Stormstrike damage has been 7k.
Nothing to say about Healing Surge, Of course i can easily go up 70/80% with 1 Healing Surge, but literal, in the next Global, i am 30% of my HP Again.
I think you can draw your own conclusions.
