Of course, that's up to you - whatever you like best. Everybody has a different way of working, everybody has a different waypointing style; and I think that's definitely positive.
Here, have a look at that. I rewaypointed 2 spots: The area right at T spawn (up to that wooden gate) and the passage over that log to the little camping area (from T spawn, through the gate, straight towards the stairs and then right over the log) to show how I like jumps and stuff. You'll see what I mean once you have WP on. Watch how smoothly bots can jump there and how little nodes you actually need...
and of course, there is not one connection more than necessary, as you will see. Don't overwrite your work with this one, just look at it and take it a little inspiration or whatever...
Oh, sh*t. I forgot you can't upload RARs here. Well, I just renamed it to ZIP, but it's still a RAR archive. Open with WinRAR and you ought to be fine...
