An RMB is a way to display your best builds. A way to have others recognize your work/see your thought processes when you make a build. It is not a way to throw out your gimmick build that you made while eating breakfast. Nor is it somewhere for you to bash others. If you're rating the build, it's for you to provide constructive criticism of the build. It's not for you to call it stupid just because you don't agree with something within the build.(Thanks, Prop. I'm adapting everything.)
1. Do not post an incomplete build. This means a build that doesn't have Runes, Masteries and Items at the same time. 2. You don't have to give your champion an introduction, but it always helps to set the mood, and show you know what you are talking about. 3. Do not post here if you're a build hipster. People will most likely use that build to test or for fun. 4. Expect constructive criticism. You can ignore criticism/suggestions and argue them, but don't go too far. 5. Don't post if you aren't going to listen to suggestions. This is not a FLATTER MY BUILD. 6. Contrary wise, if all you're going to do is bash/circlejerk don't post. 7. Including pictures would liven up your thread, so consider it! 8. Please base your RMB's competitively. Runaans Hurricane on a Melee won't be accepted, for example. 9. Actually using the build before you post it would help you to better understand what exactly needs fixing, or help you understand the criticism you are receiving.
There are a few things your RMT must/preffered contain, and these things are as follows; 1. An 'Overview' section. --At a Glance is the section in which people see the lane you're going to, all six items, 30 Masteries, Rune book and Summoner Spells on a given build. They are showcased merely with images. 2. A Build creating process. *This can show your mindset as you were creating the build and better showcase the roles of each item, mastery and rune, and also possible edits/changes the reader can make if they decide to adapt the said build. 3. An actual analysis. --This is a given. An RMB must contain a detailed and in-depth analysis of how your build interacts with your champ and the team, and possible matchups. This provides the information of how the build works as a whole. 4. "Build like this if/ Pick this Champion if*" Why should your build be used? What functions does it enhance? What playstyle is best to use it? *If you've given your champion an introduction, why should you pick it? *Not mandatory, but preferred.
Someone has already described it very well. I'll just make my small adjustments.
http://leagueoflegends.wikia.com/wiki/League_of_Legends_Wiki is the absolute best place you can go for resources, descriptions, and everything about a champion or item. I strongly reccomend using it.
http://www.championselect.net/ is a division of Solomid, which lists champion's common strong and weak picks, as well as potential lane companions. It is also a good place to look at.
http://beta.lol.fanrealm.net/6GGgMqT5wNIYFGUKDrkZ/champion-select Here is THE place to go for stat calculation, if you're feeling lazy and un-mathy, you zetta sons of digits.
Hopefully this project, aside from being COMPLETELY adapted from RMT and from Neo's thread, works out for those League of Legends players in the forum.
I might start with one of my own builds in this format, as an example.
