I had some thoughts about the control scheme used (pertaining mostly to combat).. I don't know if it was planned to use the same thing as V1/V2 where you target something with left click, all abilities are directed towards that target or if you wanted to try something else.
Might be nice to have WASD for movement and it looks like that's what you were going for with the prototype. What about diagonals? I think anything less than 8 directions will feel clunky.
As far as using abilities, each one could be classified as Direction / Targeted / Area.
Direction would be an ability you use that ignores your target and will be used in whatever direction you're facing. Swinging a weapon would be an example. Swing in front of you with a 1 unit range and a 2 unit arc or whatever. Bows could also use this, but maybe you map the bow to right click and when you right click you fire in that direction (would be more finite than the 8 directionals)
Targeted would require you select either a unit or location with your mouse after using the ability. Maybe casting the Firestorm spell at a location or Shock at a unit. These abilities could also be mapped to a mouse button so that right clicking a target/area would use the ability on that unit/location.
Area would just be something that triggers in an area around the player. I can't think of any V1/V2 abilities that use this. No target needed, no direction needed. Will hit in all directions at a radius when triggered.
The system has (some huge, obvious) flaws but I think with tweaks they could be fixed. One flaw being.. this system promotes button mashing and will probably take quite a bit more to process. I feel like this is a needed step away from "Target a unit, press an ability", but if we go back to that then so be it.
Please note that like all my posts, these are just ideas. I'm thinking out loud to try to stir up ideas and discussions.
