Nah Fizzs all about being very sustainy and fucking up teamfights, his E needs a nerf, doesnt fit his role and makes him too versatile for a champion thats supposed to be a melee bruiser.
Dont give up on Miss Fortune, shes really good when built correctly (my recommended build against the other strong AD carrys such as Cait/Kog/Graves: Zerkerboots Bloodthirster Phantom Dancer Inf-Edge and depending on their team either another BT or Banshees Veil/Guardian Angel). Shes my favourite AD carry and can definitely shine against the right team.
Also about Leona, play her as support. Thats the most fitting role for her atm, her damage is too weak for a solotop. Shes a good supportpick when the other team doesnt have a strong healer like Soraka or Taric.
Ive been trying out some new supportbuilds lately and found that Yorick, Maokai and Evelynn actually work really well as a support on bot. It heavily depends on what the other botlane chooses but when you have the right amount of aggression, it can definitely work. Been winning 2 of our ranked team games with that.
jungling is rubbish now. You can't keep up in levels, though it is super easy (full clear on the jungle with 1 pot!)
Morello already said that they are gonna tweak some of the goldgains which really suck atm (5 gold @ small wraiths lawl). Other than that I think the concept of the new jungle is great, it just needs some adjustments. As Maokai Im able get to level 4 in 1:50 now.
