Training room
What do you people think of training room? I was thinking something like using duel credits (so 5 max per day) to enter a room where you can select your sparring partner, choose number of stars, rank,level, and most importantly, choose all the "local nodes" (up to 10 max lets say), even increase persisten charges, basically artificially create opponent. That way you can spar with enemies far stronger than maxxed 5/6* some random player has, and it's much easier and practical to find a sparring partner (now you have to use line app or search randomly for opponent). This way people can test new champs, which increases a chance of buying them; youtubers can showcase that certain champion in certain matchup, and not to mention it's super useful for players in AQ, AW, quests..
