Thanks for your response! :)

Would you be able to share the editor files in that case? I would really like to take a look and at least make those changes for myself or if there's interest upload them here.

To keep it as similar as the original arena testing league, I would opt for just duplicating the five AI teams and formations instead of introducing other preset formations so I can double the amount of games in one test run.
Great work @dzek! Really curious to test out some things that I always wondered about :D

Not sure if this has been mentioned before but does it make sense to add more human and AI teams to the save file so we can have more matches in one run? I don't know if there's a limit to human managers per game but if not, I was thinking of increasing the league to 20 teams? 10 human and 10 AI, so either duplicating the existing 5 AI formation teams or testing against other formations. If this does not have extreme performance impact, then I guess it should speed up the testing process.

Also, I intend to test in the following way but I'm not sure if this is fine or has some impact on RNG:

1. Load save file
2. Freeze with FMRTE
3. Load tactics for all managers
4. Go on holiday with all managers except last one (the two boxes are ticked)
5. Create new save file
6. Go on holiday with last manager

So every time I do a test run, I would only have to "manually" go on holiday for one manager which speeds up things a bit more - especially if it was possible to increase the amount of teams :D
