Who should I main?
Hello, so I am stuck switching between champions trying to find one to main. I am good at 
Zed, 
Rengar, 
Diana, and 
Malphite. None of them just really stand out to me and makes me want to take them to ranked. So position really doesn't matter to me THAT much, just no supports. I'm looking for someone who is:
-Strong through all parts of the game (preferably mid-late game, but still decent early game)
-High damage output through burst and consistent damage
-Decent sustainability
-Good mobility for possibly roaming or dodging skillshots
-Not a "noob" champion that can be mastered after 1 game
-Someone who takes practice to really master and learn
-Good kiting
-Can carry games if played right
So all of these mixed into one champion would be perfect, but if that happens to be nobody, then at least most of those. So good damage, decent sustainability, and strong throughout the whole game. Thanks in advanced!
(lacks the early power, loses burst dmg in the mid-late game, and kiting)
(lacks sustainability)
(Mini Gnar lacks burst, but has everything else)
(Lacks kiting potential)
(you don't see these guys carry all that much and lacks mobility)
(Lulu has everything, but that's kind of her job)
(What he lacks in mobility his ult makes up for)
