Really nice guide

my opinion.
after trinity, take defensive boots(merc or tabi), sterak and go full lethality.
most of games I feel it is way more effective.
crit is too expensive and only one crit item is not really good, it start beeing usefull with two of them.
lethality items grants DMG CDR and stuff like move speed(yoummu) and vision control(duskblade)
sounds better then crit overwall.
good job on this guide btw.

You did a great job researching match-ups for Gangplank, I see you really to play as him.
Even if the content is great, you could add some images or highlight ("[[" and "]]" around names) to the text to make it better to read.

Nonetheless, I really appreciate people who know very well their champion, because it makes really fluid guides!
