This skill says that it consumes 12mana/sec. When I'm holding it down my mana decays at more like 4-5 mana/sec. I can literally hold it down and run through everything for 30+ seconds before my mana even gets low, meaning everything dies long before this happens.

Not to mention you are invulnerable while using the skill... so you sit there and run through everything while it can't attack you and you won't run out of mana.

This skill seems broken, anyone know if it's working as intended? It's pretty boring too, I'd rather not use it.

Maybe because you have some base mana regen.

yes it's broken

Yeah I just did my research on some others forums and the skill is indeed broken and going to be nerfed. It is not draining mana as fast as it should, regardless of base 4% mana regen. Not only that they will be fixing the invulnerability aspect of the skill.

I wouldn't advise putting points into this if you haven't already, it is a cheap gimmicky skill (boring as hell too might I add) that is going to be nerfed bigtime.
