Hello,so i've been thinking about maining ahri and im curious about what runes,Summoner spells starting items to take in different scenarios.

Runes:

i saw 4 options which is:
-Eletrocute-sorcery (manaflow gathering)
-electrocute-inspiration ( opgg says cookies rn and and cosmic but i saw minion demat or timewarp as an alternative) ((is minion demat needed at all,cuz i feel like ahri can one shot waves without it))
-Aery-domination (taste of blood,ultimate hunter)
-Electrocute-resolve (i've seen this very rarely but curious if its actually needed or not sometimes)

Summoner spells:

TP maybe against mages who have heavy poke and long range?
Ignite vs most melees and/or easy/weak early to kill no sustain champs?
exhaust into assasins? (zed,fizz,akali?)
is cleanse even worth it?
Starting items:
is doran ring fine everytime or do i need sometimes corrupting potion?

Thats all my questions/thoughts,hope we can help out eachother :)
