Best league

How can i know which are the best (most competitive) leagues for each category (50%,75% and 100%)?

League search is so unefficent... 

You can't.
We lack of players also because players can't find a more precise league. 

This might be a good start

Surprised nobody has advertised their league yet

Me neither, I have seen someone advertise their league on a suggestion, lol.

I knew that but it's not up to date 

I saw that as well. Technically, nothing illegal, but was surprised to see a moderator no less advertise their league there.


Here is the post in question; Turn off tier in League

I wasn’t talking about that post, Like M. Truche said he was trying to help, I was talking about someone suggesting there be a option to enable a two tire rule and someone said “join our league we have one” and posted there league. 


Anyways, what I would suggest for you Matteo is to either use that forum post, or I don’t know if this would work, but see what league has the lowest reputation for the time you would like to race since that would make me think that most races you would have various winners and different results.
