While it’s nice that you have different options for movement skills when using WASD, more customization would be appreciated. It would be great to be able to individually select for each skill whether it follows direction or mouse.
Shadow Rend is a great example, because it acts a lot like an attack, it is better to target with mouse for better accuracy. However, you can’t do that without also changing Evade to mouse, which feels unintuitive (especially for ranged attackers). Something you may have overlooked is that shadow rush makes it a long-range movement ability, yet the setting “Short-range follows movement” still applies to it. So a short-term fix would be to designate it as Long Range when it is like this.
