Join Amerika Erwache. Trust me it's one of the most badass alliances here in call of war.
It's ranked #11 in the world and its junior alliance, Amerika Erwache 2 is ranked #64 in the world so no joking around.
I have also applied in that alliance and right now going through an evaluation match.
And this is one of the best things I like about this alliance that unlike ordinary alliances that fill their slots without any evaluation, these guys are real serious about quality rather than quantity.
The community there is also very nice and helpful people.
