Can you give a little (maybe a lot) more info on which fight/fights in LFR you are referring to? I can guarantee that the difference in output from your 47-56k to his 100k is not due entirely to gemming/reforging. That being said it never hurts to have the proper setup.
I'll try to help you get Mr. Robot to give you a decent setup to work with and maybe someone can help tune it to make it more optimal.
I don't know how familiar you are with Mr. Robot so I'll try to be thorough! To get you started go load up your character in Mr. Robot and under "Choose you gearing strategy..."
open the drop-down menu and select "PvE: Hit Cap Build."
After you've selected that click on the "Edit Weights"
button to the right of that drop-down menu. There is a box for you to enter a value for the Haste soft cap
you want to reach and with your gear that value is .1252
so type that in. Click "Save"
at the top and then click "Optimize"
on the main screen.
Now when I ran this, the program put you at 0.11% under the hit-cap. This isn't a bad thing and it is up to you if you want to have the program put you over the hit-cap. There is a way to force Mr. Robot to reach the hit-cap and you can do this by clicking "Options"
(Has 2 yellow gears on the top) and at the very bottom there is a check box that says "Force Hit/Exp Caps."
Check the box. While you are here you might also want to check the other boxes that are applicable to your needs such as "Exclude Expensive Enchants"
if you are on a budget. Click "Save"
at the top when you are done. This brings you way over the Hitcap (0.34%) and again its personal preference if you want to be 0.11% under the hitcap or over by 0.34%.
From there just reforge where it says to, buy the gems/enchants and put them on the equipment specified and you will be good to go.
To get the best setup you'd need to have your gear run through Simcraft and I'm too lazy at the moment to do that for you. This would give you better stat weights to work with Mr. Robot or whatever reforging tool you prefer.
Get back to us with some more details on the fights you are referring to because it sounds like your problem might lie with your playstyle.
P.S. If you haven't installed it already, go get Affdots and thank the heavens that someone created it.
