I understand that, I'm pretty sure my question was clear though. 

I want to see how much the new hero unit thrones will get will improve production stats. 

Oh ok ... you would need a lot of screen shots ... I can tell you for this game it increases the resource production a lot ... for food over 500% and other resources not quite that much ... hopefully someone will post screen shots for you.  There are shaman levels and then shaman skills ... and the skills there are I, II and III for resource production ...

I can't give you screen shots.  Doing some research here is my best guess on the bonuses for a level 60 shaman and everything legendary.  If you pick a single resource I think you only need a level 51 shaman.

Food: 120% (abilities) + 520% (skills) + 45% (armor)

Lumber: 250% (skills) + 30% (helmet)

Iron: 250% (skills) + 30% (boots)

Stone: 250% (skills) + 30% (weapon)

Silver: 60% (abilities) + 190% (skills) + 70% (2 x amulets)

Resource Production: 10% (abilities) + 20 % (skills)

Gems: 6 new equipment equal 18 new gem spots, max 60% in 3 different resources.

Runes: 12 spots available, each resource has a rune that gives 15% at legendary level.

My calculation using Viking Helper is that it will cost at least 2.6 B in each rss and 2.9 B in silver to research legendary runes and 100 M of shaman power to kill ghosts for the runes and then a ton of silver or gold to fuse all the fragments into legendary runes.

here is my shaman

i hyperfarm food and silver but i am mainly a yielder... this is why yield, capacity and speed is important for me... my combat speciality is spy, so each piece of armor is with spy attack/defense/health gems...

And this shaman is far to be done... for the fighter, there is the shaman inga who is better fit and other type of armor for your type of troop

plarium is adding new type of armor regulary... with time, you will have a piece of armor of each type for the ressource that you hyperfarm

You were close about 2.6b of each rss but it's way more silver. 7B silver at least to get to legendary mb even a bit more. You prolly didn't see but you need offense defense and health with shaman to lvl 8 to go further down, its really tricky how they set it up. I will complete it soon, mustered all the rss.

Also the energy you will need varies. I assume lvl 6 ghosts will be generous and they don't drop a wide range of things, just pick the thing you need and go for it. A high lvl shaman helps too at lvl 58 where I am you can take almost every skill the shaman has. I will personally go for attack runes of my troop type. I have 1.8m shaman energy ready I will see from the start if its not enough for leg i will go for rare, even the rare attack runes are very very dangerous.
