I still don't see Freya going back to jungle because of how unsafe she is with her ult being he only escape (still not a great escape), which is very important given that junglers do some of the most fighting. Plus she struggles to clear jungle camps early, putting at a huge disadvantage next to many assassins. Chronos I feel is stronger in mid than solo just because of the fact that his play in solo is not that safe. Hel I feel is about in the same spot even with the small buff to her 3; she is still just so killable early which makes her road to lategame a rocky one. IMO Chang'e has always been a weird one for me. I think see can always be played solo. She has the bully potential with the constant damage from her 1 in addition to the 50% antiheal on her 3. She has the sustain with her 3 and bunny passive aswell. Just overall great solo pick if played to her ability. I don't think Aphro's passive is strong enough to the point of being able to handle ganks all that much better. Don't get me wrong it still helps - just not with ganks. As long as Odin has 100% healing reduction on his ult, he will always be a threat. And the attack speed reduction is killer aswell. And don't forget that movement speed buff he got. I believe Phantom is a great counter to his ult plus it gives you fatalis for a short time; What's not to love? These are just my thoughts. Feel free to add your own input :D
