Still a little new here so maybe I missed a thread about this already.
I heard people say that Runemage is fun but really not consistent unless you are VERY skilled at the class.
In order to help consistency, I had an idea that may or may not be helpful.
What about if after you cast a spell from memory correctly, it leaves an after image of that spell on the screen for you to cast again. If you can trace the afterimage then you get that spell again no matter what.
For instance: you cast fireball before a pull to have it ready. You shoot it, and there is now a faint outline of the fireball spell in the air in front of you. Now all you have to do to keep casting fireball is trace that outline rather then try (and fail) to cast it again.
This way you can have a few spell casters who can guarantee some more consistent DPS and the complicated part comes when they try to cast a different rune. It’s still hard the first time, but after that it’s not so bad
Just a thought!
