I have now changed the build and some other things, hope you like it better now.

Just a heads-up, not every reader is going to bother reading through your guide. If there's something significantly wrong with your cheatsheet, it can earn you a lot of downvotes. Try to make sure your builds at the top are as optimal as possible and explain any applicable alternatives in the guide.

Damn I wish I could be as brutally honest as you sometimes throatslasher. I'm not voting though , I don't want any beef with random people on mobafire.

I literally instantly downvoted your guide.
dorans blade start. bad.
no last whisper. bad.
triforce. bad.
maw. bad.
exhuast. bad.

Literally, I saw no last whisper and exhaust, and instantly downvoted. If you can't get something as basic as those 2 things, I dunno. Don't play adc.

Dont know what you voted or if you voted at all, but it stand clearly in the guide that you dont need to follow the build, every little item. If you think that Guardin Angel is better for you and better in that situation then you ofcourse buy it. Dont know if you read the whole guide either but do it thank you.

I sound so angry my comment here haha =D, but try read the whole guide and dont just check and vote after the build ^^

I like the build except Maw of Malmortius should be replaced by Guardian Angel

For the first, read the whole guide instead of just check the build, thank you.
Trinity force, underrated but really good item on Sivir so no reason to complain about that.
No reason to place Last Whisper vs Black Cleaver, both are good items. Then it stands in the guide that I got no reason to not use Last Whisper so you can change it with Black Cleaver if you want. But you proably didn't read it.
Phantom Dancer as last item, no you usually don't put it as last item but you usually do if you want to switch it with Berserker's Greaves.
Guardian Angel is good on Sivir but I search for items that gives you both AD and defense in this guide. Think it stands somewhere ^^

And once again, don't put items against each other. For example Maw of Malmortius vs Banshee's Veil. Its just stupid to do of the reason that both items are great in different situations. If you face Malzahar and he is feeded then just counter him.
Read the part over the items where it stands "Don't just buy these items just because they are in this guide, this build is a good overall build etc"

Can tell you that I have been putting ALOT of work in to this guide, do one yourself instead of hang around on Moba and complain on others builds and not reading the whole guide.

Meh.

don't think this is a good build.
Phantom dancer for last item?
trinity force? (note: procs 150% of original ad not bonus.)
last whisper > Black cleaver (if the enemy team isin't stacking armor against ADC in late game then GG.)
Guardian angel is not good on Sivir???? :O
GA is on of the best defensive item on ad carry. (also QSS & Banshee's Veil.)
and defensive items = alive longer (against assassin's and stuff like that.) = more DMG.
if you get mahlzahar ulties you, then your Maw of Malmortius wont save you but all 3 other items will give you an benefit. (1 out of 1000 scenarios were these 3 items will help you more that Maw of Malmortius.)

sorry for wall of post but IMHO I think this guide needs work!

Thanks =)

Best Guide ever! :)

Thanks! Awesome that many people thinks so and can take help of it. =)

Great guide :)
