Yeah, a glavier must have fire as the imbue skill, because it does much more damage then lightning and ice, and glaviers are meant for dealing damage.
Since you are 40, it wouldn't be that hard to reset your skills, but it wouldn't really be a walk in the park, so as i see it, you have 2 choices, spend some time gaining those skill relocation stuff, or you could make a new character, but getting your new character would take much more time then to reset your skills.
I would just reset skills.
