It would be nice to get hard BOTs in order to create a real challenge.
It would allow us to experiment builds facing realistic enemies, without having to annoy real players with potentially failed build experiments.

Achievements :
As far as I know, there is still no way to use achievement points, no specific rewards or skins, and that's sad

Random pick :
It would be nice to get the option of picking a random God, maybe after selecting role to avoid weird team compositions.
