As of right now, all abilities are set to "Quick/Smart Cast" by default without any range indicators—point your cursor somewhere, press the ability on your hotbar, and it activates right away in the targeted direction (for most of them)... assuming "Invalid Target" and "Target not in sight" don't get in the way. It would be helpful to have different settings that alter how we can cast abilities: Normal Cast. (I.e., prime an ability by pressing its hotkey then click a entity/location to initiate it.) Quick/Smart Cast on release. (I.e., same thing as the default except the ability will not activate until its hotkey has been released.) Knowing the ranges of our abilities via visual indicators would also be really helpful. This could be done several ways: Hovering an ability on the hotbars could show how far away it can reach/be cast as a visual radius around the character. Normal Cast could show ranges by default once the ability has been primed from having its hotkey pressed. Quick Cast w/ Indicator. (I.e., if an ability's hotkey is held down, it could show the range of that ability that moves with the cursor—if applicable.) Lastly, holding ALT should make it possible to Self-Cast applicable abilities regardless of where the cursor is located, and pressing RMB could cancel primed abilities for "Normal Cast" and "Quick Cast on release".
