Hello longtime lurker, lost my old account that I had in tbc with alot of contributions so finally decided to make a new one.
The druid one is quite minor but I havent seen anything about it so though I'd make a post. Did a quick search but didnt see anything about this warlock trait either. Should be pretty well known if you met a warlock in arena recently tho but they're more scarce in the current meta so might have slipped under the radar for many.
First off the trait Inevitable Demise - Spell - World of Warcraft
Warlocks stacking 3 of these does insane amount of damage on 100 stacks. Still havent been nerfed.
Picture is taken by me after a rated arena so no bg buffs or similiar.

Second one is a bit minor but I havent tried it with 3 traits just 1.
The trait Lively Spirit - Spell - World of Warcraft is behaving wierd in arena with certain talents.
Normally if you have it in dungeons and lets say you pop hero on a boss. Spam globals so you get maximum value from it and ofcourse as many stacks as possible. This results usually i around 9-11 stacks with hero.
Altho I was healing arena and I noticed I had 15 stacks. Without hero or any crazy procs. Been keeping an eye on it and you easily get over 10 stacks in arena even from not using instants on every global.
I'm not 100% what makes this stack so high but my best guess is if you run tree of life, spam regrowth and choose the talent nourish. Nourish - Spell - World of Warcraft it might actually count as 2 spells being cast. Also tried testing it in duel but it did not work as good as in arena. You get around 112 int per spell cast during innervate with one trait so if someone stacked 3 of these and got lets say 15 stacks that would equal around 5000 int.
Well thats my contributions for now. Thank you for reading!
