Suggestions for improving Rouge Legends

The biggest problem I have with this dlc is that runs last wayyy too long and get repetitive very quickly. The main culprit of this is the absurd amount of rounds in each level. Imo each level should last like 5 rounds max and work something like this:

Have a pool of like 150 different rounds with unique bloon patterns and difficulties. When a level is generated, it chooses 5 random rounds based on how far into the run you are(It's not gonna like give you a ddt on the first level of stage one ofc), the contents of which you can see before you play that evel.

This isn't a perfect solution but I think it would drastically reduce the amount of time spent on each level and let the rounds feel more varied and random while allowing for more strategy as well.

Idk let me know what you think
