current lvl 25
i never get any brown/green items from chests

all from elites and only 2 from act boss

I was considering the signet as well...
but to fully utilise leoric's signet, u need to be properly geared.

"20-30% bonus exp gain"

we should usually have 75% (NV) and if u are going for (can afford) leoric's u probably will have a 27-29% gem in helm.

The cheaper ones will be low 20s% exp gain.

All in all with NV and gem u will be gaining  ~200% and with signet u will be doing ~220%.
If using the signet does not make u kill 10% slower (from losing dps/survivability) then its worth it.

Alternatively, increasing MS or getting SOJ for wiping elites faster can be an option. hahaha

above is just my thoughts/opinion. not proven. hahaha

Leoric's Signet
Legendary Ring
Critical Hit Chance Increased by 1.0%
Increases Bonus Experience by 20-30%
Increases Gold and Health Pickup by 7 Yards.
One of 3 Magic Properties (varies)
+27-35 Intelligence
+27-35 Dexterity
+27-35 Strength

the cheaper ones will definitely be low-20s.

anyway. i already experimented. i took out one of my rings. i calculated my xp/hr then i multiplied it by 1.2... it is slower for me.

i also experimented with lacunis... didn't work out so great for me either cos i was using the cheap one with lower resist and no crit. can't maintain fury.

no budget to try SOJ yet. haha

but do whatever works for you

normally u will be doing 100%. but with bonuses u will be doing ~220%...
Not +220%.

actually i have 1K dps spear with Aspeed 11% and CD 75% slotted.....if i put that into my char ill be around 97K DPS unbuffed already...

but yeah its just me...i can buy some of the weapon right now..and get that 100K DPS..but i felt to myself i must upgrade the armor first...so in the long run..i wont be sacrificing other armor accept for weapons...im trying to narrow the upgrading process to just weapon for future upgrade here..

therefore been looking very closely on the glove and witching hour...i have my lacuni with 80 dex 80 vit 70 AR....but i need to find a replacement for that lost of CC (currently my bracer have 5 CC)...glove is the answer..and that witching hour will be the final stroke..to reach at max a 90K unbuffed and thats with a shield..after that just buy cheap2 weapon..can even reach 100K dps already..if dual wield..

p/s: thx for complement bro...hope u guys could reach there soon also..
