よろしくお願いします

Regarding this: Yoroshiku Onegaishimasu is the traditional greeting when you meet someone for the first time. It has multiple meanings but in the context of joining a party, it means "please take care of me / nice to meet you".

Polite to use this when you queue with JPN players. You can drop the latter (お願いします) if you want to appear as more casual, this is your preference.

..just incase people aren't familiar. Use it!

Great work man.
But i can't find the - "Please use Limit Break - AOE/ Single". Deeply require this as almost my half run with japs is without using LB lol.
