Lifting would be pushing pulling, lifting, and holding things with strength and technique.
Basically those other Strength checks
- Force open a stuck, locked, or barred door
- Break free of bonds
- Push through a tunnel that is too small
- Hang on to a wagon while being dragged behind it
- Tip over a statue
- Keep a boulder from rolling
I understand the difference.
My point is that if you make it based soley on imagination, well everyone has different imaginations.
And you are totallying about the imagination of a LARGE group of people of various backgrouds with no frame of reference.
It's not inherently goood, It's not inherently bad. But you ae building inconsisency into th system unless everyone in the group is the same. Inconsistency that the DM has to manage and can be judged for.
