I think the following options should be added:
- No Cooldown
- No Resource Costs
- Jungle Mode
I think it would be nice if you could setup the game to either have no cooldown or resource cost. Besides being a fun game, you could also be use to practice Flash jumps, skill shot ults, etc.
Also consider adding a custom game mode where you can control two heroes so that you can practice jungle techniques on your own.
These modes wouldn't necessarily give IP or win of the day IP, but would help us improve our skills.
