In relation to this topic perhaps an interesting one would be is the following:
Do people view balance by position, arch type (adc, tank, mages etc), or by champs?
It seem to be that Riot is looking by positions/arch types rather than champs for agency and players are looking at by champs rather than positions/ arch types. Because the top 3 champs in each position might be balance vs each other. (see pro games) Then once you look at each position/ arch type the champs aren't remotely close to balance.
put a cylinder on the table on its side. Put one light source from the front and it projects a circle on the wall. But the light source from the side and it will project a rectangle on the wall. Half the room yells circle the other half yells rectangle. But the truth is both are wrong.
So is the game balanced.... yes by positions but No not by the champs within those position or arch types.
Since riot has yet to define Balance or the power levels of champs on a quantified scale (relation power on a number scale) it seem to me that this isn't a important issue to you. Look at the power level of new champs to older ones.
Often times Balance can relate to having fun or not during the game. I enjoy watching the academy games 100% over the pro games. They started with Sion and other things first that made it to the pro scene. They also play on the current patch rather than older ones that the meta is set already. They are trying new things and difference champs. Watch a LCS game and then an academy game (this is to the players not riot) then you will understand that the choking unbalance of positions and champs are the whole issue atm. Same champs, BS power levels and able to snowball out of control leads to boring game play. Expression of the play skills through the champs they like leads to exciting, positive and involved game play.
But first and foremost YOU need to balance position and champs balance. And is there a difference and how so. This will also help with moving champs from positions.
rant: You will get more people watching all games if Academy games spread them throughout the week. Heck let them play Mon, Wed, Fri. They are all at the houses. But a camera to let use watch them. Show the games. Put some of the announcers with them. (They actually have great personality that work together. Some act dumb, a$$holish, smart, etc etc. Great together. Sure they are newish to it. But wow some serious potential there. They Civic War act/game was really put together well. Props from someone that always bashes you guys. I have fun watching them. I can log on and try what they tried. We are on the same patch. This is your golden goose that should be "balanced" around. This is the middle of the pros and solo que.
Lastly....... Fiddles rules
