Legitimate problem for beginners/low elo with an easy fix.

The problem is as follows, so the player picks a champion for jungle, but the game doesn't have a jungle build for that champion. it suggests a Doran's Blade. The jungler proceeds to lose to the jungle monsters. Even more commonly: A player picks a champion for support. However the game doesn't suggest a support item. It suggests Doran's Ring. The team ends up with no wards, the support ends up poor.

Considering many champions in the game have starting items for lane, jungle, & support. I see no reason that all of the champions in the game cannot have recommended items for all 3 scenarios. Yes, even Support Yasuo should have something like a Relic Shield recommended. Jungle Lux should have a Hunter's Talisman. It's not good, it's not meta; But players can take hundreds of games to learn about why these items are important or what is meta (in the case of support items, they can take years...).
