There are tons of easter egg legendaries and epics in the game now. Maces that looks like shields, star wars helm, ring with +5% experience gains, etc that are guaranteed drops for all characters.
Idk how “menacing gold band of celerity” is more damage than Slith Primal ring which has … is it 10% extra damage to beastskins - a common monster type in act 1 and 3
If you farm Martin for his medal, your damage will go sky rocket again.
No idea why you changed shoulders, the green ones you had were 10 times better. Try to be color blind, an item is good if it is good, not if it is blue, green or purple. You previous shoulder gave +3 BWC and much more resistances. Look:
sure it has a tiny tiny amount more armor and hp, but it is not a game changer like the green shoulders offers.
You could start use components now, here is a guide about those for beginners Component Setups before Endgame
And attribute points, try to spend into physique, like keep a buffer of 10-15 points unspent - rest spend in physique. It is good that you keep putting points in the Demo mastery bar, keep doing that 
Get some points in blast shield too, good safe passive skill to become almost immortal for 4 seconds. Like get 5 points it should suffice in normal.
Finally, do not work to get “Imp” aim for “Solael witchfire” devotion instead. When you get the EoR axes, you can reset the devotions or back track to follow my " How to get the final build devotion map" in the guide. You kinda need the energy regen from Tip of Scales, since you are not using the Mana infusion skill from “Bone talisman” (make sure to pick up the elite and ultimate versions of that relic…)
