I liked having my dark archangel wings, I liked having spectral guise, I liked having the fade glyph, I liked void tendrils, I liked having psyfiend in the regular talent tree, I liked having halo (before the animation got sped up so much you could barely see it), I liked having fear ward, I liked having actual off heals that didn’t make me go oom in 5 casts and that actually healed more than 10% of my hp, I loved old shadowform, I loved shadow orbs, and I loved devouring plague as a dot nuke.
In terms of what I like now? Shadow crash I guess.
