The deodicorous (however you spell) collects stone rather quickly but takes a very long time to tame and the saddle won't be unlocked for a while after you have stone tier housing.
Introduce the Sledgehammer a tool specialized for breaking apart boulders into stone at a rate somewhere inbetween a metal hatchet and a deodicorous, the sledgehammer would also be a pvp weapon with a long windup heavy damage dealer/and or torpor inducer similar to the primitive club, the sledgehammer like the metal hatchet and metal pick, would also be able to damage wooden structures.
I absolutely love ark but sometimes I feel the trailers are slightly misleading cause they leave out the part where survivors grind for several hours hacking at stone and trees gathering resources. The grind is important because it makes you appreciate what you spent the times to gather but sometimes it feels as though the grind gathering resources is a bit extensive especially when you are an early tribe and have few Dino's. Also the grind makes it too much work to decorate a house or put detail into it because it is simply to much work for what is it worth for most people which is why most ark servers are covered in plain square/rectangle bases
Introduce the Carpenters Desk a structure similar to a smithy that is placed in your base, the carpenters desk would give a a discount (25%-40-%) on the resources it takes to build wooden (walls,ceilings,foundations, etc). There would be different tiers stoneworks desk for stone tier, and blacksmith for metal tier items. The desk would not be overpowered because it would require survivors to bring resources back to base to craft with the discount opposed to crafting on the go and would take the edge off of the grind gathering resources and might help some tribes keep playing after they get raided because they can more easily recover with the desks (we all know getting raided is unfortunate at the least). The desk would also make more people to put more effort into making a more creative and scenic base.
Just some ideas of mine for the game, arks my favorite game and has an amazing development team and it would be really cool if we could spend less time hacking trees and rocks apart and spend more time tearing our fellow tribe apart
