Ok about the guide:
1) Maybe add a pro about her saying that she is one of the best gankers early game
2) Some of the formatting is screwed up for me (the nqb's and the pictures screw it up), it looks like this:
So if you got the Alt-Tab spoiler fixed then i'm guessing that it would be a good idea to put the pics into spoilers too, its neater with spoilers anyways.
3) Scepter could be added to the item build as optional as it gives her some survivability and more burst damage, but it's up to you scepter isn't really necessary.
4) Add a table of contents with with links to different parts of your guide for easier navigation (anchor and goanchor tag). Or just add it at the end when the guide is finished.
5) The formatting is neat, clear, and easy to read.
Looking very good so far, PD needs a good Lina guide badly.
EDIT: Linking items to their descriptions through pictures isnt necessary as 95% of people that will read you guide know what each item is, however for those 5% of people it might help, but it really is unecessary.
