Doom isn’t even necessary for mage tower. I did it a couple weeks ago and talented as many demon passives as possible and then just focused on mechanics. It was pretty easy like that.
From a design prospective i hope the season 1 set that made your next hand of gul dan insta cast and do more damage becomes a talent.
But honestly, what they need to do for warlock is scrap everything the did since aberrus, and go back to s4 shadowlands, and start from there, because god knows wtf they are doing now.
Can demo not be the best lock spec for 6 tiers in a row? maybe?
