Aliens are meant to kill humans are they not? Humans are meant to kill aliens are they not?
Intentional TK is an offence is it not?

Humans are able to, by using their in-game weapon, kill other humans. Yes, TKing is an offense insofar as TKing is a form of griefing, since it is listed as a subset of griefing according to the sticky. However, in the semi-rare case in which TKing is not griefing, then I think it would be natural to say that TKing is not an offense.
Furthermore, aliens are meant to help each other, and humans are meant to help each other. In-game, since killing your teammates is not lethal, as evidenced in the story (humans are clones, aliens have the overmind), it makes perfect sense (to me, anyways) that helping each other can in fact including tearing your teammate's body to shreds.
To be honest, speed-building does feel a bit "cheap" to me from a gameplay perspective (but not from a story perspective) due to the fact that it can go around the build timer given a clear spawn queue. However, there are some, admittedly small, penalties to doing so (but great enough to prevent people from doing this in scrims in most situations, apparently) and there are not a great many situations that it even can be used in, thanks to the BP queue. More importantly (and the reason I bring this up) is that even this is different from the metagame (such as /team s) however, because it is part of the implicit
rules of gameplay, part of the in-game, and makes sense apart from the concepts of computer and player.
Its not about how the pieces sit in the end, or whether you win or loose, but how the game was played.
EDIT:
Also,
But yeah, common sense tells me that if it was wrong, admins would have at least warned me (as well as others) about it ages ago. Why then is this "common sense" among the admins only materializing now?
I think its mostly because it wasn't noticed, since a big yellow !specme isn't printed across the screen. For some reason this didn't happen when people had to use the !specme command, I wonder why this practice is only materializing now...
