Thanks very much Shadow_Light

So I have looked at the guide again. I've seen the update and it looks a lot better now. Yet there's still many things you can improve but I can see that you really want to improve.
Upvoted, and I hope this guide will get better and better. :D

Veiregor, the Point is, you didn't read the guide well. Riven is easy to master at lower elo's. Since you are able to carry whole games with her, without doing big Plays. I think, there is no right answer on what t max up with Riven first. Q-max matches in my playstyle so i would recommend to max the Q if you want to Play how i tel it here. If you have your own playstyle, you don't Need to look up a guide :)

Thanks to Shadow_Light for ou constructive critique. The guide is, as in the title said, not finished yet :) I'm working over it all the time!

This guide is the same as all of the other guides ive seen so far
Y max Q since it doesnt lower cds,dnt do alot of dmg ?u can use ur Q only for activatin passive or close-gap or knock-up.
Riven easy to master?easy to master?!cmon man lets be honest...u cant make feaking plays with riven before having 500+games with her ;)

zephyr? poooooo

Well I wouldn't call this a great guide but it has potential. First of all you should really work on your coding. I really recommend you to read the BBCode Guide which helped me a lot. DOn't overuse Colors. It makes it hard to read. Overall your guide could be alot better visually.
Your content is fine but the guide is a bit short. I didn't say that you should add more text and make it to 20 pages because there are a lot of good short guides here but you there are several things missing. Like for example a match-ups section and an Explanation of gameplay. I see you covered early game tactics there but for a player completely new to Riven that wont be enough.
Didn't vote for now. I hope I helped you a bit.

Thanks to Logarithm, i will think of it and probably change it after!

Thanks to king boo311, the guide isn't finsihed yet, i already planned something like that :) But thanks for your constructive critic!

Thornmail: No.

Havoc : No. Fury , yes.

Flat MRes Runes: No, unless Riven mid.

Early Tiamat: No. You push the lane like crazy with just your Q. Hydra is fine though, after first major item (its active is more burst).

Sunfire Cape: Unnecessary. Other items are better for defensive use. Magic damage aura not useful for any offensive use. Only good on splitpushers with poor waveclear or champs that already have auras.

Walls of Text: God no.

Frozen Mallet is missing as situational defensive.

I see a lot of potential. I bet once you learn more fancy coding the content will look a lot more appealing to look at. Otherwise I enjoyed it, although I do suggest adding a Gameplay section with Early Game, Mid Game, and Late Game instead of just putting laning information into a few item parts. I'll check back every now and then, tell me if you updated! I won't upvote yet, goodluck on this guide! :3

Thanks to you Blingen97, im still working on it, so just return sometimes to see the new stuff :)
