It would be great, if you could choose wether you want to fight with the matched opponent or not.
Its annoying, if you want to do the Dojo-Raid and know beforehand that you cant win, because your partner is to weak. There is no possibillity to stop the Raid. You have to wait untill all Heros are dead, wich takes a few Minutes.
I would suggest a “cancel” button, you can press after the matching. If you dont hit it, the Raid will start after 5 or 10 seconds.
