I feel like the only comments I can give in these guides are the same...

ARMOR PENETRATION CANNOT REDUCE ARMOR BELOW 0. That is all. :D

Guide is flawless, I have tried it over and over again (Great games everytime) +1

amazing, 11-2-6 first game, they surrendered at 20, and doing well otherwise. WOW this is planks true job it seems.

Guide works perfectly fine, item build is good and jungle route didn't really pose much of a threat. Carried the game 14/6/20 as well so thanks a bunch!

+1 :)

Your theorycraft sure favors parrrley too much. My guide is not perfect, but what you are saying is flawed.

Looking at the base parrrley cooldown, it's 6 seconds. Raise Morale has a base of 25 seconds. That already throws off some of your calculation since you have one less parrrley rather than an exact 5 because we decided to have a number that is perfectly divisible by your 5 sec parrrley, thus allowing us to land one more nuke. Not very fair.

Now, if we go with the runes and masteries mentioned, parrrley is 4.56 second cooldown, while Raise Morale is 18.33 -- that's obviously is favorable for parrrley, or so it seems. The problem and why I don't take parrrley first is because it has a mana cost. If you tried my guide, you would know that you run low on mana using all of your abilities by the time you hit red.

My last point is, you should be getting a leash from mid, while top lane helps with a couple of hits. Raise morale will boost their dmg too.

If you found your way favorable, then my all means, go for it.

Parrrley does more initial damage than Raise Morale.

To compare the two skills, lets looks at the damage over 25 seconds.

Parrrley: ~5 second cooldown. (54) + 20 dmg @ lvl 1
*not taking into account attack speed loss from firing parley*
25seconds/(5 sec cooldown) = 5 shots
5 * (54+20) = 370dmg

Raise Morale: ~25 second cooldown, 7 seconds active. (+20/hit). 18 seconds inactive (+8/hit) @ lvl 1
Gangplank's attack speed is .694, (.708 with masteries)
In 7 seconds gangplank attacks (7*.708 = 4.956 times) Lets assume he gets 5 attacks.
In 18 seconds gangplank attacks (18*.708 = 12.744 times) Rounding up to 13.
5 * (20) + 13 * (8) = 204 dmg

In addition, there are 5 more opportunities to crit with the parrrley build.

Great guide that make sense.
I went on my first game in a ranked, i carried it: 15/6/23
Gg, +1 from me

Insane guide, i just think gp is a lil bit useless for gank before lvl 6, but i did pretty well on my first 2 tries. 3/1/18 and 5/1/10. ^^

Really awesome guide love it.

I gave it a +1 but one thing I would like to mention is that I think 15% spell pen is better than 1% attack speed (and I know you mentioned this in the guide), but seeing as your passive is magic damage as well as your ultimate (I believe), 15% spell pen would net a much larger net damage increase than 1% attack speed, which is ~.007 additional attacks per second

Ever since his buffs (Slow on his dot and Parley procing his dot) he has in my opinion become the best ganker pre level 6 (maybe even after) with His aoe speed buff, the ability to ignore CC, Good damage, and a slow that can stack up to 35%. With his ganking power he levels up faster than most junglers if played right.

Definitely +1! I think this is a great guide, and it needs to be seen more. You did a very great job, more people need to see GP's jungling capabilities after his recent buff. If you don't mind, please rate my Swain build.
