hmm... for most part. you can't really call this "common knowledge" it's definitely not something you see everyday.

1 reason this isn't popular is that most players sometimes won't risk doing this just in case it backfires and they just waste a ward.

putting that aside. a uncommon gimmick is definitely not a reason for you to be so impolite to others. if you learn knowledge. share it. instead of using it to look down on others.
