A very simple and quick mod I made to help me (a new player) distinguish the different class types to make playing Astrologian easier. Thought maybe it could be useful for others. Should only affect the HR icons for 29/30 classes (No icon for Blue Mage). No icons for any crafting jobs edited.
Tanks have blue shield icon. Healers have green plus. Melee DPS have the red fist. Ranged physical DPS have red arrow. Magical DPS have red lightning bolts.
