It was mentioned that we lived thru it when we were new. In my case this is only partly true. I became very frustrated when spawned killed repeatatly. But I am a loud mouth and said something about it. Lucky for me often there were senior players in game that took care of the spawners for me so i could learn and enjoy it more (thank you Big Tex, wig, duckwing, and others like them). Also I was lucky to have senior players to give me some basic advise and encouragement (ty seven, calvin, and others like them). Finally, I've been lucky to play often with players that play fair ( ty manfred, nachoo, miss hell, and others like them). I understand that new players are life blood to the game, and I try and emulate the example of the players that helped me. I speak up when I see spawning, I offer advise to noobees, and I don't kill aspiriants in most cases. On occation, I have asked all members in game to "let aspiriants fly" so they can learn to enjoy the game.
I challenge all players: do something to help make the game fun for noobees.
As for the question of tactics, use your best judgement. Choosing to tank on deck against a team of level 5 and below is different than doing it against a group of level 20 and up.
