Magicka NB, sell me on destro staff

Wing

preface, I have run a magicka nb for a long time and its currently sitting at V14 so I am aware of most of the basics.

however, I have never run a destroy staff despite being magicka based because I find NB skills just cover everything a destroy can do and usually better, that said I only run two primary characters, one stam dps/tank, this one magicka dps/healer. and so want to try out destro staff.

that said I cannot sell myself on it so help me out here.

as far as I can see there is no point, impulse does a slight bit more damage then sap but sap has fantastic incoming healing. destructive reach can be replaced with cripple for cc, wall of elements with dark path, even crushing shock with funnel.

is there any benefit or synergy im missing? sell me on this.

The class has 0 elemantal dmg abilities, so it's hard to syn w/ destro. That said, the night blade passives/actives open the door for a shadowy disguise/destro heavy attack type burst since it's not a channel. Try out heavies, shooting star, crushing shock w/ empower after a respec into ele dmg instead of thaum for some very destructive ranged magicka burst. use grim focus like frag, cast entropy before it for 15-25k hits, plan your burst around fear and empower. you are going to be reliant on healing ward, cloak, and your hp bar so staying invisible between heavy's and movement is how you mitigate.

The benefit is long range partial heavy attack weaving with Funnel health which adds a crap load of damage.(around 30% difference between no weaving and a flawless weaving) It also helps by adding dots if you go for a Skorya based dot build.
