I think amount of player in a map is so wrong

I am new to this game and I moved from Delta Force which is completely different to this game. It is more fast-paced and fight happens all the time. Usually there is a set amount of allowed people in a map and you get that %90 of the time. For example for zero dam it is 15 players and you will get at least 3 teams of trio and rest could be anything from duos to solos. But in this game, especially in armory, it either spawns a full squad and rest duo/solos or trio and rest solos duos which full squad pushes to armory -> loots -> extracts. They leave without firing a single shot which is kinda frustrating as I love to participate in fights. I hope they address this issue and arrange teams more evenly
