Got it!
Thanks again Trev!
You just made me do maths with lower EE items and INT amount on charm. :wacko:
Int on a charm to off set the negative 25% of a Charm in the ACC slot is pointless.
However, depending on OTHER mods that the "+50 or more" Intelligence charm using on main slot, benefits the ACC charm or your character BUILD (melee/healer or melee/caster or caster/healer or the Tri-Hybrid which I have tested), not the character class, Fighter / barb / monkey etc.

+% Armor Pierce (this is good for casters & melee)
+X Critical Strike (this is good for casters & melee)
... Note: they do NOT affect your healing capacity.
-X% Mana Consumption (this comes in handy a little)
+% Critical Flux (this is for defense and a % chance to reducing any Critical Hits that a monster activates attacking you: Melee &/or Casting)
There are other mods that can benefit that +50 Intelligence charm to be used on main slot, BUT, it does NOT compare to switching the EE charm on ACC slot to Main Slot and higher levels like 50+
And Trevor answered all your questions, I am just adding some other things to why you COULD (not would) use an Int charm on main slot.
