I'll have to join the crown in the fast blinking also bothers me. I have severe motion sickness and anything in the UI that suddenly wants to pulsate at rapid speed (like the old treasure loot icon) tends to trigger it.

It would be nice if combos abilities lit up solid in one color (bright white/yellow I believe it is now?) and reactionary abilities lit up solid in a different color, such as hot pink or green. That way I could know that it is available to use but isn't part of the current combo succession I am carrying out.
