Pal, let me give you a little nugget of advice that I discovered quite early on in the game: duplicate loot, isn't always the same. Allow me to explain more, I opened 2 large chests 1 after another and out of both I was really lucky & got Mindchill Staff & it wasn't until I went into my inventory screen that I noticed the DPS scores were different, one was higher by 3, not much I know, but it got me looking at any other weapons I get duplicate of, I always go over to the crafting screen & see how much DPS I have should I decide to slot a rune of the same value in there. You may be getting lucky in more ways that one, especially if those Griffon Longbows have a higher DPS.
Hope this helps you a little

Your post seems sincere enough, so I won't be too critical or judge too harshly. 
However, This "little nugget of advice", would probably be of better use, given to a player that is newer to the game. I have already opened thousands of large chests.
I would hope that it would be pretty common knowledge, to people like me, who have opened over 650,000 gold worth of chest.
Also, when addressing someone, especially someone you don't know, starting out with, "pal", "bud", "sport", or "junior", can often be taken as a derogatory addressment.
I don't know if you meant it to come off sounding that way or not, so I'll give you the benefit of the doubt.
My little nugget of advice for you is, perhaps you shouldn't address people that way in the future.
As I stated in the opening line, the post "seemed" sincere enough, so no harm no foul.
