I mean, Mages have that cool freeze ball effect in frost, Shaman has lightning, Rogue has shadows, Druid has dem greenish particles and Starfall/Starfire, now priest have cool looking shadowform, Paladin has hammer and consecration that looks and sounds great, Warrior has its own too.
None of those are "boring" effects, yet Warlock, who has Demonfire a widely used and kinda trademark spell, is a .... a greenish boring small ball, if you cast it on a demon or an enemy is just as boring. I mean if you buff a Demon it should be more spectacular or something.
What do you guys think?
No balance discution here, just talking visuals.
Also Blizzard changed the falling Infernals from Golden Jaraxxus background and that makes me sad.
