Is it necessary to practice adaptation for DOTA2 rapid casting?

Yes, it may be easier for beginners to adapt from scratch, but it will be more difficult for old players to get used to traditional keys and it will take longer. If you fight by yourself and hit passers-by, you don't need to change, but if you fight professionally, you can still adapt to rapid casting because it is conducive to rapid operation. I hope I can help you!
