Ok so here's my dilemma, I have no idea which champion to buy. I was thinking Vi
or Zed
but i'm open to suggestions. It's worth noting that i'm a Jungle main but I also like playing Top a lot. Here's my Champion pool-
Annie
Dr.Mundo
Elise
Evelynn
Jax
Kassadin
Kayle
Kha'Zix
Lee Sin
Maokai
Master Yi
Nasus
Nunu
Renekton
Shen
Xin Zhao
Zac
Ziggs 
Zed can go Mid, top and jg. he is technically a jungler but almost everyone plays him mid. it really depends on you and what u want
Vi is awesome! :) also she is on sale right now :)
i say vi cause shes a jungler and a top laner
Mundo is very overpowered and has great get away rate, mundo will teach you how to get away and make good fast decisions. Do this with other champs to learn new skills. Want to get good with an adc buy ashe to start and try adc, same with ap carry. Good Luck
Ok I've Narrowed It down to Zed, Hecarim, and Vi
Get Zed for the jukes man the jukes!
I would definitely vote for Vi over Zed. She is an amazing jungler right now and can be played top if you really want to. Her ganks are amazing from lv6 on and even a pre 6 flash + vault breaker is highly successful.
2 other champs that I think are more than worth the investment in the current meta are Shyvana & Olaf. Both of these can be played in either role and are obviously very tanky. Looking at your current champ pool it seems that you lean towards tanky champs so they would be a good fit also.
if you like jung then vi and kha'zix are really good for that and they can top really well. i would narrow it down to those 2. i use them both a lot!! hope this helps:)
You should look at maphite or maybe even tryndamare i would go with nasus tho. He is op and if you ever play ranked he is the first one to get banned. All of them are good characters its just what your preferences are to play with. It depends on being a tank or a mage or fighter!!
