Thank you, and yeah, I get that alot..
There are certain builds that are VERY viable, but people think they are bad because when ever they see a teammate DO the build that player doesn't know HOW to do the build, or they just try to pick it into ANY situation
In my case, it is support
and in about 25% games i go support lux, I get to hear my ADC go, "Wow, you are the first support lux i have ever had that is actually good"
and while i do love the complements. It saddens me that so many people frankly don't know HOW to do it properly. So much so that it gives it bad reputation.
