Ive farmed schemers eyepatch for ten hours,ten hours seems a little to long for a specific item.I know it's rare,but it seems that it's to rare.

Now it's been twenty hours(not exaggerating).And the schemers eyepatch still hasn't dropped.Does it have to do with the fact that I'm farming on my swashbuckler?

Drops are random. You can't manipulate the drops. Just keep trying is my best advice. Seriously? Only 20 hrs.?
I've been farming Miranda for months.
Story Time!:
I was farming Cadmus for 2 weeks, when I finally gave up and decided to play on my Musketeer. And when she went to promote her Mag-7 companion, what did she get on her first time through the Caves of Ruin? Yep, those so rare Blades of Shade!
So, you see, its just random chance on the drops and nothing to do with who you are using or what you are doing( or not doing ).
The Good Luck emote won't hurt your chances, either.
