Abilities we miss

I miss life siphon on Rupture Alpha and combo attack:stun on Bluefist.

 

vitalize is a nice split enabler that isn't as available as before.

 

Speaking from a predominantly IS player:
Flashbomb on Dwarven Roughneck.
Defender on Ward of Ailur.
Accrue on Redfist.
The previous barbarian racial prior to Warchiefs.
Divine Favor on Leoss Magnate and Northern Cross Militia.
Tunnel Earth (3) on Dwarven Excavator
Attack: Fire on DMC
Bastion of Mobility and Tailwing both available at the same time on Griffin Rider.
The Displaced.

 

I also miss Life Siphon on the Rupture Alpha - it was what made me really like the rune.

I miss being able to take 2 different 'hidden' abilities on Kanen Tracker.

I also miss Kiergana's speed...
