i have question with master ???

hello every people .
First, I want to thank everyone who answered my question

-I mean what happens to the master when the 4 months ended leagues and all characters will be converted to standard,

-The master, I reached level 5 on the standard, and in the rampage I reached level 6. What will happen to the master level when rampage converted into standard ?

You will get all your Masters at the highest level of both 1eagues. In your case it will be level 6 when you merge to Standard.
