It would be nice, if you do some BB-Coding work. Your guide is pretty confusing.

Just like Joxuu I don't really like your copy-pasting. There is no spaces, it looks super heavy and everyone cleary see that you did'nt put any efforts into it.

The runes: what's up with the single seal of ability power and the single mark of ability power ...
It doesnt make any sense even if I consider Janna's ratio.

I understand what you're trying to establish with the masteries, but just like the runes its a bit weak and you dont even bother explaning it.

The items you suggest are not bad, but the two ''purchase order'' that appear randomly kinda confuse me. Were you too lazy to put a title or a note ?

Im kinda dissapointed by that guide, and promising to anyone who follows it to reach Diamond is lame considering that half of your guide is not understandable.

Im sure that you can do better then that and highly recommand you to read Jhoijhoi's guide to how to make a guide.

You did a good job copy-pasting everything from lolwikia.net, including all the picture sources.
Your runes, masteries and build are pretty bad anyways.

I use this build and i love it.
The tips and the tricks are great.
The Ap build is the best on Janna.
My shields are op.
The masterie build and rune build are perfect.
