a good thing to have is one major main for your main, say orianna mid

then you want to have one champion that you can play very well on each lane, say irelia top, nautilus jungle, jinx adc, nami support

then you want about 3 champions for each lane that you can play decently well in case you can't play the other champs or they absolutely don't fit your team

i'll give you an example of what i have in my champion pool

top: mainly irelia; fiora, maokai, lulu, quinn as back-up

jungle: mainly nautilus; zac, amumu as back-up (i barely ever jungle cos im really bad at it so i only have 2 back ups)

mid: mainly orianna (also my main in solo q); lulu, leblanc, annie, vel'koz, karma, lux, ahri, cassiopeia as back-up (mid is my main lane when i play solo q so i can play the most champs since i want to have quiet a variety, although im not good with assassins except for leblanc)

adc: mainly jinx (also my main in ranked 5s); ezreal, graves, varus, caitlyn, sivir as back-up (adc is the role i play the most by far, it's the role i usually play in normals and always in ranked 5s, and by now i can play every adc decent but these are the ones that im the best at so im comfortable to pick them in solo q, although i actually often pick ezreal or graves over jinx incase they have someone like blitzcrank leona or thresh as support or they're team has vi or lee sin etc)

support: mainly nami; lulu, blitzcrank, karma as back-ups
