Curious about keybinds

Hello, just lately I've been really wondering. Does everybody use the default set up that League offers for keybinds? I've seen a lot of streamers, asked some of my friends too but everyone I know so far seems to use the normal keybind setups being Q,W,E,R for spells. F for flash and D for (whatever else summoner spell you need) items on 1-2-3 etc etc. When I started playing League I found the normal keybinds a bit inconvenient, maybe because I just came off of playing other MMOs. So the Keybinds I use is A,S,D,F for spells. Q for Flash E for whatever else sums I need. W for trinket. 1-2-3-4 for Skill Level up and Z-X-C for item number (1-2-3) in that order. Does anybody else use a different set up? if so please share so I can see what other people are playing with! ^-^
