If you wanna try out Team Builder, it is only live on NA servers for a few days, so play it while you can, I HIGHLY recommend it. However, I do have one complaint. Evidently, not very many people wanna play ADC in Team Builder, which is weird. Personally, I’d expect a crap ton of people wanting to finally be able to “instalock” their ADC role and champion.
In Team Builder, you can chose your champion, summoner spells, runes, and masteries just like normal. However, what is new, is you get to lock in your lane and what position you’re playing in that lane as well. Good bye tilt? Let’s sure hope so!
