The game is sorely lacking new modes.
I think just ripping off some of the modes from war thunder would work. That or having more variety in the types of maps we get, as in the only real dynamic maps we have are the train ones, and arguably defense/attack modes where the front line can progress.
I think a ‘simulation’ mode would be great for all the ‘real’ locations depicted in the maps.
Historically accurate objectives beyond who is defending or attacking and from what direction would really spice up the excitement of gameplay.
And even forcing accurate load outs in a hardcore mode accessible outside of custom games would give credit to all the accurate weaponry
A practice/grind mode against bots that match your br/ skill level would be great as well for the new progression system. But perhaps that would be too easily exploited.
Having an ‘encirclement’ mode where the teams are unbalanced in number in favor of attacking encircling forces, but also in that the defending holdout has better weaponry?
Like many of my suggestions this is a lot to ask and the devs of this game do very good already.
But adding new modes would give players a lot more to stick around for and explore and that’s what a lot of new players want. I remember being underwhelmed with the amount of content the game presented to me until i dove deeper over multiple revisits. Perhaps more players would stick around with more diverse game modes.
