You know, for all the shit the balance team gets
I dont see a lot of people actually using their brains and thinking of how balancing actually works. If they add, remove, or tweak something in a champs kit, dont expect it to be solved right away. That's absolutely and incredibly stupid to assume it'd be fixed. They need game data, they cant just sit at a computer, change a value, and sit there and say 'well this is fixed lol.' It needs to be properly tested by tons and tons of people so they have enough accrued data to decide if it's alright for now or if it still needs a change.
Add on to the fact that they need to gather thousands and thousands of different games with sometimes just the ONE aspect they want to change, and you've got some fuckin work ahead of you. People with all different skill levels, playing in different game modes, playing in different ranks with different play styles? Yeah, let them absolutely just fix it right away. I'm not advocating that they can't do no wrong or that they're absolutely always on top of things, but I'd like to see you sift through all that god damn data and then have to make an educated guess as to where to go next. Not to mention they're looking at probably a large pool of champs at any given moment.
tl;dr: Get off your little pedestal about the balance team, they have shit to do and they'll get to it when they can. They're not brainless idiots and they take what everyone says into consideration. They also have their own internal squabbles just like any other human beings. Stop being little god damn children about it.
(Edit: it also seems like an almost thankless job, so I'd like to say I appreciate your efforts, and dont think that there arent people who don't appreciate it either.)
