is a ton of fun. Quite easy to learn and your enemy will find it difficult to get close enough to you to do any damage. He out ranges essentially anyone in game.
Also
is probably the mid laner I've had the most success with, he's super easy to pick up, the ultimate lane bully, and can delete almost any champ in a 1v1 if he gets his combo off. Great pushing strength, Never have to worry about mana in lane, and he can also farm jungle by himself at a very early stage for extra gold.
Personally the first mid laner I learned to play well was
. Hes a great lane bully and you don't see him incredibly often so a lot of people don't know how to respond to the constant poking and stunning- depending on what skill level you're playing at.
He can also be played as, or more successfully in top lane, it's nice to be good at a champ that can play in either solo lane well. He's also a safe pick:
Passive: Stuns and gives you energy every time you place a third mark on a target (each ability adds a mark, each 5th attack adds a mark, ult adds three marks in close succession)
Q: Medium range skill shot
W: Does AP damage and adds an additional mark to all targets who are already marked...has great range. Also causes each 5th attack to deal bonus damage based on AD.
E: This is why he's a safe pick- almost as good as flash on a like 20 second CD, also gives a small Armor/MR boost.
R: Deals massive damage and adds three marks to everyone in range, stunning them. This is another reason he's safe, if anyone tries to all in you, or you get ganked, simply ult and E--> escape, or kill them. Has a lot of potential to turn even a 2v1 gank into a favorable situation.
The problem I've found with Kennen is that all too often my team mates underestimate my ult and fail to follow up after I dash in and stun everyone. You're choice of items is also a little bland early on, you essentially HAVE to rush Zhonyas unless your team can eat the other team in a team fight without relying on your ult (rare). In those cases you can have a little fun and build pure damage or even hybrid...Gunblade, botrk, nashor's, etc
is also great fun if you can get a couple kills. Requires a little more skill, but has always been one of my favorite mid laners.
