What do you think?
Sure. Can work well with the new infernal Knight Set. There are some threads about it already:
you plan on playing melee or ranged i suppose? with a caster it will definitively not work i think, it lacks damage skills, and even with a weapon-based build, you have too much debuffs and not enough dmg skills imo.
at the very least you need an AoE for clearing trash mob, especially early game before you unlock Fissure and Meteor Shower. also i see now reason for not picking Callidor’s Tempest for that build but you may have your reasons 
I think it’s underwhelming (deceptive imo) cast animation combined with not so great performance in early-game makes people believe it isn’t a good skill.
yes you might be right (now that you said it, i remember the only time i try the skill and wasn’t impressed at all)
people should read forums more thoroughly then 
Same reason why people bash BWC so much. Early game it is pretty weak so they just assume it sucks end game also.
I thought the same about BWC, until i realized every once a while it breaks mid-air (enemies can destroy the projectile, cool mechanic though). Not saying this makes it bad, it’s just kind of frustrating to use in some cases. Then again i never made a full BWC focused (Infernal Knight was the set name iirc?) build yet
