Hello everyone, welcome to my Gankplank Support Guide.
I want to start a come back of this rarely touched Champ, that's still my favourite.
There's one problem that made him vanish from our Teams and that's his lack of mana
while not having so much utility like other Toplaners.
In Season 4 there are new Support Items that make him a valid pick.
To show you a decent guide for a try out in case you dont believe me that's what I'm here for.
Everyone likes a nidalee that actually hits her spear though GP is much easier to play. You probably haven't yet encountered the poking hell of parrley!.
You will poke them until THEY want a truce.

Quint of Lifesteal :
Like I said, there's his lack of mana. To make a up a counter poke autohit when you hit your Q in a bad way to also be hitten you need the lifesteal to sustain.
This Quints make your damage higher than the enemey adc on you with 1 hit.
If you've been to greedy for a moment and need to back down a little hit creeps with autohits in a way to help your AD carry farm and get some health.

Mark of Armor Penetration :
Backup damage against tank support that need to be poked until they can't engage anymore.
If they do anyway, ignore them, eat some fruits, and help attack the adc.
Glyph of Mana Reg :
The usual pick would be Flat or Scaling Magic Resist. Don't rely on being defensive.
Your pokes have to come up all 4 seconds.
Seal of Armor :
Another Rune Pick to get less dmg from the ADC who at best play after 2 Q's from you be all aware of your damage and pokes.

[+] High Damage and Passive Burn Out
[+] Nice income by getting assists or kills on other lanes
[+] ConCC-Fruits
[+] Free time for your ADC to farm

[-] Few Warding
[-] Early Flames of your team because they have never seen a GP support before.
[-] Late Flames of your enemies because they have never seen a bot lane feeding GP support before.
[-] Greediness and skill have to balance in your ways
[-] Not tanky

This is my first build here on mobafire and I don't expect anyone to like it's layout.
If I got time I will update it with some fancy img's.
The whole purpose to publish one is to show you an alternative support that is realy funny during the whole play and not some stand by "let's see what happens" champ.

I hope you enjoyed it anyway and try it out !

Greetins from EUW ;)
