Team Builder - A Summary

1. Right now, you can only queue up as a single role and a single champion. One of the main goals of Team Builder is to ensure that queue times/Champion Select times remain reasonable. We understand that players are willing to wait a bit longer to get a better match or better teammates but we don't want players to wait too long either--it's a tricky balance. Because we're trying so many new ideas in Team Builder, we're starting with basic functionality for many features in Team Builder--only selecting 1 role, only selecting 1 champion, etc. As we collect the data and determine things like the current wait times to get a match for each role/champion, we can figure out if there's additional value in giving players even more flexibility and allowing things like multi-champion select or multi-role select.

2. Players can adjust their Summoners, Runes and Masteries in the group lobby. Once a team composition is settled and a team is built, your team instantly goes into loading screen against another team. (There is a Ready Check Button)

3. You do not get to see the other team while adjusting your Summoners/Runes/Masteries, and only see the opposing team on the loading screen.

4. Because we're taking development one step at a time for Team Builder, we haven't incorporated bans or drafting in Team Builder. We're going to work on the core experience first, then slowly expand and test additional features of the Champion Select experience. Team Builder is going to be an independent queue initially. We're trying a lot of experiments and taking a lot of risks in Team Builder, so we're taking development one step at a time. Depending on what we learn from the experiments in Team Builder's independent queue, we may incorporate some or all of the lessons into other queues like Ranked. We're well-aware and agree that Team Builder in its current form is not a good fit for Ranked, which is why if we do anything similar for Ranked, it'll probably look like a completely different feature. For example, part of the strategy and fun of Ranked is counterpicking and drafting and right now, Team Builder doesn't support those things.

5. Initially, Team Builder will be Summoner's Rift only.

6. Recently we did a PBE test of Team Builder, and the queue time data was very promising. Queue times are something we're going to keep an eye on throughout the development process. We know queue times will increase by a small amount, but the key is determining whether the increase in queue times was worth the better teammates and matches that players are getting.

7. Yes, Team Builder has a few anti-abuse systems in place so that if a Captain kicks too many players, they will put a cool-down on the Captain before they get another player suggested to them.

8. Is TeamBuilder going to restrict champion picks to roles? [–]RiotLyte[S] 22 points 1 hour ago Nope. One of the key things about Team Builder is allowing more flexibility and creativity to exist in League of Legends; for example, it was really cool to see Zyra played as a Mage, but also develop as a top-tier Support. It's very difficult to predict all the ways players might use a champion, and we want to make sure that Team Builder allows players to play League however they want.

9. Okay, so I have a question about Team Builder. Lyte stated that With Team Builder we’ll also be rolling out a smarter matchmaking system that can dynamically account for your experience with a given role, position or champion. First time playing Ahri? Learning how to be a solid Marksman? Venturing into the jungle for the first time? Team Builder’s matchmaking will take all of these factors into account. Does that mean that I will be playing with people who also don't play there roles very often, because even though i may not play this champion/role very often doesn't mean I'm going to be worse at it. and i want to matched up with people who can effectively test my capabilities. I don't want to think this new jungler I am trying is OP just because I get placed with people who don't know what they are doing. permalink [–]RiotLyte[S] 53 points 2 hours ago The smarter matchmaking will pair you up with players that will appropriately challenge you. As an example, if you were a Diamond Mage player and suddenly decided to start learning Marksman, the system wouldn't assume you were also a Diamond Marksman player. The system would try to find appropriate opponents to determine your actual skill level as a Marksman player currently, then slowly ramp up the difficulty of opponents until you're experienced as a Marksman. permalinkparent [–]jake_astarte 11 points 2 hours ago Does the system assume all champs of a similar role type will be played with equivalent skill? e.g. Marksman: Ezreal, Quinn, etc.. permalinkparent [–]RiotLyte[S] 37 points 1 hour ago The matchmaking system takes into account role and champion separately. So, it might recognize that you are a professional Marksman player, but more skilled and experienced with Ezreal than Quinn. This means the system will find appropriate opponents to help ramp up your experience when you are on Quinn.

10. New champion releases will definitely affect queue times. However, we think this will still be better than the blind pick rush that can happen. If you're set on playing a particular champion, it's probably better to have a wait than to get into a match and play a champion you don't want to play.

that's a basic summary. you can read it for yourself on the reddit link.
