I don't know if this has been asked before but since we're having a battle update i believe it's a good time to request this.

In the Challenge an Opponent part of battling, along with the stats of the enemies, we should be able to see how many times we defeated them. I know we can already see how many times we defeated enemies on another page, but seeing it when choosing an opponent would make it so much more convenient if you're going there to farm enemies, it would make it easier for us to establish our own goals. And speaking of goals, there's a second suggestion:

Separating enemies based on their difficulty they are already organized in a difficulty based way, but i believe it would be better to have a distinct separation for them since they already have defined tiers (easy, medium, hard, etc). iThe reason is the same as the other suggestion, making it easier for players to establish goals when battling.

The intention is for us to be able to go to the coliseum and clearly set our intentions, for example "today i'll try to reach 100 wins on every Medium opponent before tackling Hard ones again", i think it would be more fun :3
