I went with friendly.
Reason... Even if a team has a strong leader or loads of resources or even MUCH SWAG, it doesn't matter if you can't enjoy their company.
A team on PSO is a community and a community falters if people aren't friendly.
I do agree with having a strong leader, one that is admired, but I believe a leader should be admired for things other than strength, a good example is where the strength is used (for what purpose) and strong doesn't mean respected, respect is a thing earned through acts of strength, kindness and intelligence as a whole.
feel free to quote me on your next epic "Braveheart"esque speech (we've all done one) but credit me please lol.
