I've gotten a bit bored with my current selection of champions, and would like a new one to try out. I mostly play Renekton, Twisted Fate, Warwick, Master Yi, and Hecarim, so any champs that work similar to them would be great.
Lee Sin? Vi? Both fun, Lee Sin more skill based though.
it sounds like you kinda like people who dive, so if you are looking for a carry, I would suggest Diana or akali (it would be useful to get some mid laners anyways). if you want a tank,I would suggest sejuani, swain (you build him with tons of hp/mr/ap items), or wukong who can go either carry or tank.
Pantheon is somewhat similar to TF in that you carry more by using your ult to jump in to other lanes than you do by winning your own lane. Yasuo is a really good high mobility assassin, which is fairly similar to Master Yi.
Sounds like your More into Jungle Roles, I suggest, Lee Sin, Vi, Fiddlesticks, Kha'Zix, Elise. All good for Jungle and Laning. Fiddlesticks Non-Meta Support.*.
