Ok, another round today, but it was still quite confusing.
At first i thought that i was on defender side, but in the end it turned out that i was attacker.
Anyway, that was my map as i have joined the game.
So far i have figured out that the encircled spot is my current spawn point and i can choose between all of the green ones.
But i have no clue what the fire icon means and i guess the one with aim mark might be the next target of my side, but i am not sure about that.
At the end of the round the map has looked the same, so i have no comparison here.
A legend for the map could be an solution.
Another one is to rename the teams in attacker/defender and remove the spawns away from the flag, this leads only to spawn camping which is not that funny.
