Ok, so ive been playing league for years but it seems like pick order always changed.....for the worse. In ranked it seems as soon as i get to a series or a winning streak i get last pick EVERY game.
If i get my main roles or champs i have upwards of 67% winrates but no ill get last pick 6 games in a freaking row. Ty Riot, another way you keep people in low elo.
Main roles are good to have, but being weak in the other roles is something that will keep you from climbing. It's not Riot's fault you haven't put any effort into improving your game elsewhere.
I don't care when I pick, since I've made sure I can at least do a decent job supporting.
What I do care about is when other people on my team first pick stupidly easy-to-counter things like 
, 
, 
, etc.
Pick order is completely random, which is why Riot says Pick order is > Call order.
Pick order is randomly generated.
If you are seeing patterns, they don't really exist. You just have a very small set of sample data.
Simple enough. Learn how to play other roles. A Support is capable of carrying the whole game by getting an adc fed. Any role can carry. Learn them.
The title of your post implies a question, but the body of your post does not contain one. It looks like you understand pick order unlike the title of your post implies.
So what I am wondering what is the actually question or discussion you wish to have?
It's randomly generated. It's not based on your performance. You don't like it? TOUGH!
No one ever wants to discuss the merits of being last pick. You get to see who everyone else has picked. It allows you to adapt and no one can try to counterpick you. You still don't like it? ** TOUGH!**
So you don't always get to pick your preferred exclusive role in ranked. TOUGH!
Get good! Start practicing with other roles and champions! Learn to adapt! TOUGH!
