Witch ascendancy classes need some work, here's my thought

I think you guy know the trick to sustain high Demonflame and also plan to nerf it so I won't be commenting about that in this thread.

The Problem: Infernalist's demon form have what is basically PoE1's Dash skill--minus the cooldown, this already made the class faster than most build in PoE1.
My Solution: Make the super dash have a cooldown and while on cooldown make her dash at regular dodge rolling distance.

The Problem: Despite Infernalist themed around using fire spell, her all damage can ignite passive is almost useless to them.
My Solution: If the goal is to make her versatile and can ignite with any type of element, maybe add visual effect or even replace the old one with fire? Like, make the Comet summon fiery meteor instead?

The Problem: Blood Mage, who should be good with bone spell, but her best passive 15% base critical for spell do not affect bone spells at all, instead it do best with fire, which have low base critical chance.
My Solution: Maybe make it adds base critical chance for spell instead? (like what critical weakness do)

The Problem: Blood Mage's mandatory passive do more harm than good, especially on earlier level when you first got her ascension. Overflow life seems like a good idea, but her constantly using them to cast her spell make it useless even in mob clearing. I only managed to make one successful Blood Mage build by not casting any spell at all and using Arctic Armour to ignite and bleed enemies, once I cast a single Comet, the benefit from her overflowed life is gone.
My Solution: Make her life cost use her Original lifepool first before the overflowed life. This will fix her spell casting cost (the life part) while still maintaining her first ascension passive's benefit and it's downside.


PS. I like the rest of witch ascension passives, some may need balancing with the number which should be an easy thing to do, but overall they are very good designed.
