Yeah success does depend heavily on the quality of the players.
I also tried Post Scriptum on a Steam free weekend a while back, the players there equally took the game very serious, I had some German guy yelling at me for jumping in a tank and doing a kamikaze run at the enemy lines, was actually doing okay but I got kicked ;P
If PS has the same system ticket system as Squad then:
- 1 player is worth 1 ticket, one tank can be worth 15 tickets, each vehicle has a respawn timer which can reach 15min,
- side that runs out of tickets first loses,
Additionally one-manning vehicles that require multiple crew to operate will get you kicked on most servers. Doing "kamikaze run at the enemy lines" can be considering asset waste and will most likely get you kicked from the server, example would be some noob pilot practicing flying helis in public server crashing one after another.
So yeah, if you got kicked you most likely deserved it.
