I conjecture that the cause is the lack of rigidity at the contact point between the base and the two levelng screws. This holds especially for arms that have had their base abused by owners who overtighten the leveling screws and leave indentations in the base.
from my experience
The ET2 has three, well four areas that are sensitive to setup abuse by new owners, and those who are not aware of how it works.
The one you mention with the base and indentations from the vertical bolts from not being aware of how hard one has screwed those vertical screws down.
All leveling should be done after bringing them both up to reset. They should never have to touched again after that. if they do, the base is warped from abuse and/or there is a good possibility a users turntable is going out of level. check there first. Anyway the aluminum base fixes this problem so is welcome.
Very excessive force on the Post bolts and VTA block screws being over tightened and even closed.
I ask what kind of madman causes something like this to happen ?

The VTA block rack of teeth have been stripped by using it when the block was shut closed, and the VTA block case itself destroyed but excessive force on the bolts. .
A third being tightening the end cap I Beam cap bolt too tight could cause it to crack at the opening . I did this once years ago.
A fourth extreme is the gooseneck. Maybe tightened too tight and left on for years. A user when going to remove the armtube, puts incorrect torque in the wrong place and could snap off the cueing lever.
