Every experienced player has that one thing they wish they had known when they first started playing. Maybe you upgraded the wrong stuff. Maybe you opened too many cases. Maybe you invested too much into weapons...
Now that you know the game better, you probably wouldn't repeat those mistakes so, If you started War Era from zero today, what’s one thing you’d do differently?
Experienced players, drop your answers below. Let’s help new players (I'm guilty as well) avoid making the same mistakes!
