Keith, thanks for passing along the suggestion provided by @Smithy975.
While I agree there is logic in the theory that reducing wait time will would make it less likely to match players. However, this does not apply to the league of dragons. Since the most recent exodus, there are never players available within the delay period, so this makes no difference in this regard.
As such, I agree with Smithy, and suggest the developer would be better to hasten match-ups for players choosing to battle bots because as they are not being matched against humans regardless of the delay.
Another thought for consideration would be to have the bot strength decrease on losing streaks in the League of Dragons similar to the other leagues. This would make the bot battles somewhat more tolerable for many players.
