So I have finally decided to make the jump from 8th to AoS (Steampunk Sky Dwarfs did the trick) and I am slowly converting over my Khorne army, but I can't find some of my units.

There seems to be no entry for Hellcannons (and the GW website doesn't recognise them either). Have we lost them altogether (in which case should I run mine as soulgrinders)?

And while Chaos Ogres are in the list, there are no points costs for them. Do I use the Ogors list for them?

And while I am at it, I can't find any rules for unit coherency. Am I blind or is it an oversight on GWs behalf?
