Considering getting this game, and i have a couple questions to ask

Does this game have active australian, singaporian, or japanese servers (mainly australian) that have enough players for a full game?

Is it more like battlefield 1 or holdfast: frontlines? (i have played both)

Hows the gameplay? is it infantry based or vehicle based?

Is it realistic ww1 when you kinda are forced to stay in trenchs or unrealistic where its pretty much a constant battle and trenchs only mean shelter from shots thens its out again

Austria-hungarians? Ottomans? Bulgarians?
