Top: Olaf is a great carry killer in TFs, combination of ghost and his ulti makes him very difficult to gank post lvl 6. Jungle: One of the best jungle clear times, and a great counter jungler. Also not blue dependent, meaning that Galio can take the blue early which will allow him to dominate that area. Mid: Galio's passive makes him a strong choice against most AP mids. Brings a strong initiate, and some tankiness to the team comp. Carry: Vayne, great TF mobility, and the scariest damage output at the later levels. Support: Lulu has great poke which helps make the AP side of the comp a bit more dangerous, and a good range of saving and hindering abilities. Brings a good ultimate for the team fight. Cons: AP carry doesn't deal large amounts of damage, and will have to dominate the lane to win the farm. Vayne has short range for an AD carry. No heal on Lulu outside of a summoner heal.
Tend to disagree with this. I feel like Galio can win farm even if he plays pretty passivley (especially if he is getting blues.)
With the blue nerf though picking up all the farm is going to be difficult for a melee mid if he isn't able to be right in there. He's not going to win the farm count from his tower, but will be able to keep it ticking over.
Ashe does enough to farm and escape with quad heal from soraka. Engaging with Ult when we want to gank. Pretty OP when rammus taunts also.
