You should mention that some details of your guide doesn't apply to many servers, mostly ours.
For instance some servers have random crits enabled for saxton hale which ruin the 202 base damage. Some servers made changes to the vagineer where his rage forces sentries to betray their engies. Some servers have hales whose rage radius spans the entire map.
I'm not sure if our server has changed the original game mode so much. But the point is, this guide doesn't follow with all saxton hale servers, just ours (And possibly a few others).
EDIT: Its a pretty decent guide for OUR server, but it'd be impossible to create an
in-depth guide for saxton hale servers worldwide.
