With all of the "Generation" skills, my hotbar turns into a mass of blue. It's just one figure in different illustrations and it can be difficult to see (even when lit up) which is which. I have them separated on my controller by AOE skills and single target skills, but I'm asking as someone with low vision if something could be done to differentiate these skills just a bit more so it's not just "figure on a blue background" for all of them.
