Does anyone else feel Ahri is too safe as a champ?

Not really. While she does have a pretty "easy" laning phase it's entirely mitigated by the fact that she's ridiculously useless lategame, something so bad that even Lissandra mains take pity on how bad her lategame is.

Yes. She has everything that a midlane mage could possible want with the exception of self CD resets and mana sustain.

try to play her

she has huge mana problems early

also to do the full burst she should dive in because the range on her w and r is low

she is not useless late game that's for sure but she doesn't scale that well too, her winrate statistically drops for prolonged games

p.s. as for ungankeability i think akali is more safe, lol
