For a Rogue build, I have the following ability bindings (same keyboard configuration):
This again feels really nice to tap and/or hold 'E' for nearly-endless Flurry. Getting too hot, or want to trigger the Caltrops bonuses? Bottom out 'E', release, and re-tap to get back in the fight. Holding SHIFT so that your 'left-clicks' don't move you helps wity any 'standing still' bonuses.
For 'W', a tap will Dash, but again, get into some trouble and need to become unstoppable? Bottom out 'W' and you Shadow Step your way to safety (or to the Elite you're trying to take out first!).
What if I need to type?
Due to the remapping of W, E, R, and F, it's nice to have a second config to switch to if you need to type a message, e.g. when using in-game chat. The way I do this is to have only 2 configs enabled on the Apex PRO. This can only be done via the OLED menu on the keyboard.
Hold the media button below the scroller next to the OLED to open the menu on the OLED.
Scroll down and selet 'Configs'
Scroll down and select 'De/Activate Configs'
In the 'Deactivate Configs' menu, ensure only the first 2 configs are enabled. Config 3-5 should show an empty checkbox
Now only the first two configs will swap when using the SteelSeries Key + F9(P) hotkey to quick-switch configs. Make sure to do the above steps first or you will be switching between 5 configs.
