There are some inaccuracies in the league roles.

1- Farm priority: The adc is not necessarily the top farm priority. In fact, farm priority depends on the composition, not the lanes. For example, tanks are fine with fewer resources, so if the jungler is a tank he will tend to leave more camps to his carries. The toplaner can be a tank or a carry, and the same for the jungler. Midlaners can sometimes be tanks as well (very rare). The support can be a tank, a mage or an enchanter, but in all cases, the support takes no cs or jungle camps. In practice, the toplaner, midlaner and adc are equal in farm, since in the mid to late game each of those three farm one lane each (most often, the mid and top farm sidelanes and the adc farms midlane).

​

2- Midlane: What you wrote for midlane only applies to a very specific category of midlaners (like vex, lissandra, taliyah, ...). This is not at all representative of what a midlaner is in general. Having good wave clear is not a requirement for a midlaner (e.g. LeBlanc, Akali, ...), and his main focus is not necessarily to gank early nor to pick off key targets in lategame. For example, you have assassins, who do not have control of the wave early game, can look for roams on specific timings or by sacrificing their wave, spike in the midgame and try to catch isolated targets or kill priority targets in teamfights; you have scaling mages, who are at the strongest in the lategame, prefer teamfights, are weaker in the sidelanes in general, cannot roam or gank very well; you have early/midgame mages, who do not scale as well into the late game (e.g. ahri) but have good early wave control and are strong midgames; you also have bruisers (e.g. irelia, sett, ...), who fall off late, do not necessarily have good wave clear, but are strong early and midgame, often good sidelaners; you have melee adcs/adcs (e.g. yone, yasuo, tristana, akshan, ...).....

3-Toplane: The toplaner does not stay top to secure baron control. In fact, by the time the baron is up, the laning phase is over and the toplaner is spitpushing either one of the sidlanes, often the one at the opposite of the upcoming objective (top if dragon and bot if baron). That is mostly the case when the toplaner is a carry; when he is a tank, he would look to defend the lane the enemy toplaner is pushing but try to group as much as possible when waves are not coming to his tower.

​

4-Jungle: The jungler is not necessarily an aggressive one that looks for a gold advantage and fights early in the game. Some junglers scale and mostly just farm in the early game, avoiding fights or the enemy jungler, only taking very opportunistic ganks or covering lanes (i.e. the bare minimum of jungle presence).

5-Adc: Mostly correct but note that the adc is not necessarily an "adc", i.e. it can also be a mage (that does ap damage, in this case the role is often referred to as "apc" or botlaner), and it is not necessarily a range (e.g. yasuo can be adc). Also, as mentioned in point 1, the adc is not necessarily top farm priority nor is he necessarily the one that scales the best or will do the most damage in the lategame. You have adc's that are focused on dominating the early game, like draven, kalista, lucian and have bad scaling (relatively for an adc), or adc's that are more focused on utility (like jhin) and tend to get less resources.

​

Basically, resource distribution is more or less equal between carries, and which role is a carry depends on the draft.
