[2023] Skill icons are overused

While we will continue to add more and more unique icons for these things, sometimes it’s really good to have a similar or recoloured icon ready to go. Making a node a Flame Reave that works with Fireball? Maybe have that icon be the Fireball icon so people know immediately what it’s about. This isn’t the only reason to intentionally reuse an icon and they do get reused too often still. We basically create new icons for various things and they all get put into the node icon pool. When you see unique icons as nodes, it’s usually because those were skill icon concepts that didn’t make the cut or were changed.
