Ele Eq.+Ball Lightning+Curse on hit+Flammability=no icon

I am currently running a dual totem searing bond/ball lightning spell totem with ele equilibrium. Prior to getting curse on hit, I could affect mobs with ele equilibrium and then also self cast curse them with flammability and see the flammability icon appear hovering over the cursed mob. I added Flammability into curse on hit with ball lightning and spell totem. When hit by ball lightning, the mobs still show the effects of ele equilibrium, but they aren't showing the additional curse effect icon. I have tried this with numerous different mobs in different areas, all with the same lack of effect. The combo seems really neat--hopefully you can figure out why it isn't working quite right and let me know?

Appreciation,

Traps and Totems supported by this gem will not apply any curses even though the tooltip says they can and curses linked to this gem are disabled from being cast directly. This is still true even when using a spell or attack linked to the Trap or Spell Totem/Ranged Attack Totem support gems.

That's from the wiki - but I kinda thought the same thing. Curse on hit only triggers when YOU hit a mob - and since the totem is hitting, the skill won't trigger...

Thanks, now I understand
