Element Size. Minimap is the name of the game, so you should make it big and consider shrinking other elements to free up space. Pros always have the minimap at 100 and tend to have lower HUD size, while chat size is a personal preference. For non-desktop fellows, my settings (15” laptop, mild myopia) are HUD=2, Chat=21, Minimap=100.
Yes, that is what I found out too. I used the G240 mouse pad (said it was perfect for the G502 mouse) and it was medium size. I liked it but yesterday I got the Steelseries QCK+ but the big one. Thing is, that's irrelevant for me. I suspect the biggest problem is my desk. The way it's set up, I can't do any arm movement, only wrist.
The lower resoluation you play league at the better. A lot of pro players in league, sc2, cs, dota all play at lowest or low resolution because of the advatages. Less eye movement, you can take in more at a glance. Less mouse movement, it's faster to get your mouse from x to y because shorter distance. xJz5.
