Yes please, don't forget the mythic helms got 3 gem slot, 6 int>0.4 raw damage, even the imbued gem cap assault got less damage than the current mythic helm for sorcerers.
A bit armor boost would be nice, dont wanna loose armor stat with upgrade, and there are plans to mage buff, it will be a small step in this direction.

Rogue helms also need a bit damage buff, and a huge armor buff. Its just not acceptable that there are better helms in auction for 500 gold with +100 or more armor stat.

So my tips:
Mage helms: bit damage, bit armor buff
Rogue helms: bit damage, huge armor buff.

No recipe, no money.
