The +1 to all skills in Soldier on the Crown of Infernal Gems seems a bit strange considering the other stats are perfectly fitting for a fire sorcerer build (other then the lack of cdr%). Why no +1 to all Demolitionist or arcanist?
I am guessing Crate sees this item as some kind of intermediate helmet for fire Battle Mages/Warlords/Comandos?
Problem is that people would rather play more synergetic damage types with those class combos, so I doubt this helmet would be used much if at all.
So maybe +1 to the suggestion, that way at least someone will use it.
