This is just a thought. What if global chat was locked out for brand new players?
Of course I realize that global can be a valuable resource for information when approached correctly.
What if global was unlocked at the conclusion of the tutorial?
What if global was unlocked after a low amount of levels? Like the level 10 idea.
Make people learn how to play the game before they go into global asking very basic questions.
A level 1 with 1 kingdom and 3 troops asking very basic questions in global either gets ignored, made fun of, and very rarely helped.
These results are not what they should get.
This is just an idea.
