This guide is just a failure from the start. You can't build against your counters, they are your counters for a reason! If you can counter-build against your own counter, then they are not your counter. -_-

It'd funny that if I'm the LeBlanc facing you and you build this way, I actually accomplished my goal of shutting you down. If you build pure defenses, you will be rather weak.
Yea, sure I'll not be able to kill you, but who the hell cares. I'll go gank other lanes and will get fed from there. And since you're building pure defense, you won't be as much of a threat.

To be honest, you can't counterbuild a counterpick. The best thing you can try to do is to outsmart your enemy.

^This.

You could use some colours and maybe some icons:

Your ideas are decent but I'm guessing not a lot of people want to read them. Use the above tips to help with that.

Voted +1 for effort. Maybe start a new guide.

Would suggest you turn on comment to vote if you wanted more feedback.

might be too late now though.

Hmmm, I'm not sure about this. Ahri has a nice deal of non-bursty counters (like Swain, who can force her out of lane with her ulti), and you should probably speak of them one by one rather than be generalistic.

There are also other counters, such as Talon whom you can't face only by playing defensively, since they can gap close into your face.

Wouldn't AP/LVL seals and glyphs with Flat AP quints give a better boost for early game? as when you reach lvl 6~ iirc the AP from the seals and glyphs beats the ap from flat runes. And it's during that time that ahri starts to go around for more kills.
