because, you know when people are using skype because you know who they are. If there's GLR/TKO/BC/wH people without the wii speak symbol beside their name, chances are they are using skype/teamspeak, just because they used them in previous games such as cod, moh, mario kart.
Lol. I love how you call out BC xD. We don't use TS during wars and you can't prove that we do. Anyways, Marathon on TO is a LONG war and I don't think it's needed unless Pentagon is picked since its nearly impossible to get a capture on Pentagon. Killing Overide isn't a bad mode; its a nice mix of TR and TO. 5 on 5 and above will get laggy for alot of people and I believe that WiiSpeak adds some lag (I may be wrong, but when I use it in a 5 on 5, it becomes really laggy for me).
