I've been playing Gangplank every time my teams in need of a melee dps, and I just wanna know the best way to build him.

I usually start with brawlers and 2pots
My first trip back (depending on level of success) is avarice and starter boots with normally one Ward two pots or I get a BF sword and avarice. I get my I.e. hopefully before 20mins followed by Ionian boots.

I start my warmogs and usually by that time the games done, but after warmogs I get atmas. My final two items are usually situational defensive items (fon sunfire etc)

Am I building him correctly by going tanky dps? are there certain items I MUST have?

What about GP runes?

Shoot me ur recommendations
