I have seen a few similar posts to this, but most of them take awhile to be updated when new classes are released (or are a few classes behind), so I decided I would try my hand at making my own, sharing for anyone that may want to use them.
They're by no means "perfect", there is some overlap with the Horse/Boat icons on some classes (Dosa / Corsair in the preview link)
I am considering doing variations with color based on the class.
I pulled the class icons off Garmoth.com, and the rest was done in InkScape.
