Yes, it’s worth it. Many times over! :D
Watching YouTube videos as mentioned above gives you a good idea. You do die a lot - but you can kill a lot too, and the game moves along at a good clip. People tent to find which class suits them, which may take a little time.
Accidental team injury does occur as people are learning how to use their weapons and the controls - this makes some people angry - it doesn’t me unless its on purpose. I am having too much fun. most people say “sorry” when they accidentally kill a teammate and usually they respond “np”. There are always jerks who rage at everyone about everything - just ignore them and have fun.
And GOOD FIGHT. Oh my God, it’s so nice to play a game where even when people die, they say “good fight”. That’s the best testament to a game being good… if people are still happy after dying.
I think the good manners we see are because each kill is so much more personal than long ranged based games. With so much melee combat, we appreciate the fight and our opponents a lot more, and thus respect them more.
