The result of each battle will be affected by the following factors: 

1. The strength of teammates 
2. The strength of the player 
3. Owned hero/weapon's level and attributes 
4. The strength of opponent 

Therefore, how to realize team matching in a balance way is an important part game design. 

The matching principle Couner Fire follows is: only teams with similar game duration, win rate, and level will be matched to the same battle. 

The relevant matching algorithm will be continuously optimized according to the in-game data.
