Thank you for the Patch Rundown

all that did was tell me that the people who test the changes are cardboard 5

They're balancing philosophy is so subjective. Jarvan's defining feature is apparently his early level ganks? What about lee sin? What about shaco? The balancing team should seriously consider consulting with the actual designers and pinning down exactly what the designers were going for. That way both teams can learn from the patch. Part of what makes balancing a nightmare is how unbalanced the champions were initially designed! The designers can make smarter balanced designs (cough CertainlyT cough); the balanced teams can actually get an objective view on what they should do and not rely on he said she said who/what is OP at what time.

I bet what they're doing right now is just looking up reddit (no one looks on the boards for balance advice... let's be honest) ask a few pros and coaches and casters about what's strong and weak then move forward with their closed off "balancing."

Part of what makes them lack confidence might be because they really don't know what they're doing.

tl;dr: If they can't communicate to us, the audience, properly and confidently, just imagine how their internal communication is like. (Assuming they even communicate at all)

ps: I'm making a such a rage filled comment because I've worked with these kinds of people. The kind of people who latches on to a bad idea just because it's made by a guy with some authority. E.g.: I made an idea about X, a bunch of nooby juniors just nods their heads and goes with it, then it turns out my idea was bad. Yes it's my mistake, and in retrospect, the mistake is blatantly obvious. But what gets me mad is that we're literally paying these juniors for nothing. No constructive/or even destructive feedbacks. Nothing. These guys seem like those kind of guys.
