true it might help guilting but it doesn't mean you can get them easily. there's several things we need to understand well regarding mickey & brooms.
1. mickey & brooms is combination of 1 fantasia mickey + 5 brooms. in JP ver, mickey & brooms is usually a reward for high ranking event or top weekly lux event which ofcourse require you to have at least decent medals to compete with those whales. most i've seen is 2-3 mickey & brooms reward for top ranker.
2. regarding VIP quest, in JP, it's not mickey & brooms quest, it just broom quest which can only net you a total of 7 brooms (1 broom/day). means that you can only get 1 mickey & brooms and 2 brooms leftover. and isn't permanent quest.
3. you can get brooms usually from raid boss's avatar board node. which need tons of coin to unlock and the raid boss usually have 12 hours time limit to defeat. and it just usually 2 brooms per event.
summary, mickey & brooms is still luxury even in JP. people usually only use it on exclusive event medal or premiums that have no or rare copies. and we're talking about NA SE here. they won't release it until their wallet is full. plus i can't imagine how they will deliver the first mickey & brooms.
