witch infernalist issues

I know there is a long list of other issues that you have to deal with but I personally am having some problems with my build I have no idea if this is done intentionally but if it is then the tooltips are misleading for the build or if it is accidental then the order of application may be a issue in how you list dmg.

anyways here I go:
1)in demon form today i tried cast on crit then when i switched between forms because it deactivated cast on crit because of the reserve from demon form it caused me to crash i relogged and tried to get out of demon form which reapplied cast on crit and that too also caused me to crash so ive have to take that out of my rotation so thats one of my trial builds out of the way

2) the infernal hellhound and infernal minnions this is a bit of a two parter, the infernal hellhound and infernal skeletons obviously apply ignite i have wildfire on the hellhound, obviously those are skill gems in the long run if we assume that so my skills therefore would apply ignite getting me to my second point the cast on ignite gem isnt charging from these skills great so i stop trying to run that and run the raging skulls and that doesnt charge either this leads me to believe since i have the ring (blackflame amethyst ring) which converts fire dmg to chaos i then took the ring off and ran it ringless which also didnt help but i fail to understand why the ignite from minnions which are skills then dont trigger because you have them as skill gems and they take up skill slots and they have a reserve which makes them a "cast" skill so either the tooltip is misleading or is it there is a bug
