I'm gonna make 2 wild guesses here.
First OP do you use a lightning blitz team? second, do you often get bested my the 1010 team in Sage?
The 1010 team is the only way f2p and casual spenders can be competitive in this game by focusing on initiative once they built their teams. It does not require to spend for it and is very reliable if you have the initiative. It will even be one of the least affected teams with the coming changes in 3.0 (cough han cough).
So yea, no wonder most players choose that team. It's the only option to try and get something from sage and be in the top 20 in space time.
There will always be a meta team that will be easier to get than others and it will be the most common team people will use. This is true for all games in the competitive scene.. This wont change with 3.0 or even 4.0 so get used to it, otherwise you will be salty so long as you keep playing online games.
