Cute post. Unfortunately, we all generally play all roles. The only reason I don't get to play a lot of Mid is I'm one of those who never just picks two roles. I generally use this cool option called "Fill." If I'm going to climb the ranked ladder, I better damn well have some top/mid/jung/bot games jumbled it with my support to keep me limber.
And, what picks generally boil down to isn't what people prefer to play, but rather what is better to 1 trick to climb. The majority of players have realize by now that when they randomly change roles/champs, they average a far worse MMR. Furthermore, they've realized specific champs are very hard to counterplay, even if they are proficient with other champs. Generally
Find themselves in very hard to counterplay roles. They move around too fast to reliably skill shot, and they cc is that is point and click is few and far between, or they stack forever and fast, or they can almost undetectably 1shot you from behind. So.... people gravitate to them because playing someone like
although it may be fun, just doesn't pull 70% results because she doesn't have an unstable kit.
There are a lot of champs that are balanced by their own performance, and then there are champs that are balanced because they generally don't work well with teams, which brings good games into the loss column.
For example, is too good at assassinations. His team rarely gets assists of the kills, because he does most of the work himself. In other words, the deaths are worth the 300g for the kill, but they offer no takedown bounties to anyone else. In other words,
Starves his team of gold by being too efficient. On the other hand,
is a good team player, gets high kill participation rates, gets some kills and gets some assists. She's as middle of the ground as you go. But..... that means that she struggles to carry bad teams, because she's inefficient at sealing the kills
You'll find most Mages are middle grounders, with the exceptions being potentially
(More of an assassin),
(More of an assassin),
(When skilled, outputs high and global) And Middle grounders get less play.
There's a reason Supports gravitate to
: They are the supports who are not middle grounders.
