Yeah but it's not like you can just sit there and learn them by heart. Most people play a while, then read about it or ask what they did wrong, then play a little while more and so on. You can't take all the theory in at once nor is it useful to just jump head first, you need to mix both.
Besides, there's been some debatable advice mixed in with the useful stuff right here in this thread.
* Evolving to a bigger alien does nothing if you don't know how to use it. An experienced human can kill a newb tyrant with a shotgun, because the newb keeps missing and stumbling into walls and doesn't have the sense to run away when he's really hurt.
* The basi can be horrifyingly dangerous in the hands of a skilled player. And it only costs 1 evo. If the humans don't work together a good basi can absolutely own S1. A basi can wallwalk, can paralyse, can work like a mara and jump from head to head biting, is small enough to get by unnoticed yet has enough HP, can bite any human structure, its bite causes turrets to turn around slower etc. The basi seems slow because unexperienced players use it wrong (grab a human from the front, work alone, don't run away to recover when hurt).
* The advanced granger has a couple of means of fighting humans, it's the normal granger that can't do much. The advgranger can be quite useful in defending his base and he's actually expected to venture out of the base at times to stash away eggs or recover a lost base. His spit transmits poison (if it has it) and it will be mistaken for trapper spit, so often attacking humans will be looking around for a trapper and ignore the granger.
