Is Team Leader taking 25%, broker 15% resonable? eXp Realty California

[Lilly Fang]

I am currently under a team at eXp Realty. The broker takes 20% (have to correct here, I think it's 20%, not 15%), then the team leader takes 25%. The team leader has become a friend. We discuss everything. She has been great in helping me through the contract process. However, I also know I can call in help with eXp's broker helpline. My question is, I feel my team leader is doing what a broker should do, which is helping me go through the document and learn how to deal with buyer's remorse. Now, I have completed three transactions, which allows me to be independent without a team. One the one hand, I like to be with my team leader. On the other hand, a 25% cut is too high, considering what she does is what a broker should do; she doesn't provide me with any leads. I got all clients through my own network. 

After the 3rd transaction, what should I do? I hope to join a team/company that the broker helps me as my team leader does, but only with one layer of commission cut, not two layers.

BTW, I am part-time. I do this mostly for my own investment, but help friends buy and sell as well. I am not pursuing any outside business.
