Please swap these icons.
Action Surge is a heart and green, that's pretty universal for healing, but Action Surge is for an extra action.
Second Wind, what's that do? It heals!! It should be the heart icon! Do you know what the Second Wind icon is? It's a blue fist in the air! As if they were gunna do something, like idk maybe an action!!
It only makes sense these are swapped and it's been bothering me so much! I was sure it was a bug or mistake but it's been several patches and they are still as they were.
Please consider swapping these before release, I think it'd make the class abilities much more clear.
