My coalition is only 2 men and cant participate in the challenge tournament. 

Who told you 2 men coal they cant won this tournament?

In the previous challenge tournament my coal won 2 times against coals with 30 players and loosing just for a few points the other two against coals with 50 and over players.

It's looking clearly that you want to eliminate all small coals.

This is not riight and unfair to those they spent money to built a coal.

Sparta is a strategic game and they have rights all players and all coals to those tournaments. 

Let free the coals to decide for them participation.

I spoke with many hegemons and I heard even the draws with the coals over 10 players are fixed. All big coals except the two higher lvls have draw with low coals and the reason is to get rid of small coals. 

Shame on you.
