Right now there is a lot of toxicity, team killing, abuse of vote kicking and general negativity at the start of Conflict matches because of a divide in starting mentality between new players and experienced. Experienced players understand that building an arsenal at the start of a game is self sabotage as players will quickly drain the base of supplies and anyone who hasn't gotten on the vehicles that spawn at MOB get stranded because they have no supplies to spawn vehicles with. Experienced players will usually try to correct players building arsenals at the start of the game but they usually end up getting team killed / voted out of the game because they're seen as imposing on how other players want to play the game. This issue has been a thing for a long time now, before the massive surge of new PS5 players which have understandably greatly exacerbated the problem recently.
I really appreciate the amount of player agency that is afforded to you in Conflict but I feel like this simple change and all of the problems it would fix at the beginning of a Conflict game are a far greater good that greatly outweighs the negatives of not having that freedom to build an arsenal as a private anymore.
