From Mythbusters

Swinging Ewok Log Ram
This was the myth that the Build Team (Grant, Tory and Kari) tackled, and they did so by first devising a steel-reinforced wooden structure that could support two 10,000-pound, 10-foot-long and 5-foot-wide logs swinging towards a target in between with a combined 2 million joules of energy if raised to the proper height for testing.
During their proof of concept test, they were unable to get their preferred 45 angles for each log, and so for the full test, they lowered the logs and target vehicle, reinforced the structure and lengthened the cables suspending the logs. They also used an armored truck with the Imperial emblem to represent an Imperial armored vehicle like an All Terrain Scout Transport. When aimed at the back of the cabin, the logs knocked the truck's side panels off the frame, leading them to declare the myth plausible even though Tory reasoned that such a weapon would be hard to time and aim. As a bonus, they put an Imperial dummy in the driver's seat and targeted the cabin with the logs, dealing heavy damage.

My personal take on it is that the top part of the AT-ST couldn't be heavily armored due to topheaviness. IF it were too topheavy, the AT-ST would have issues keeping balance on terrain.

Also this thing is called the "All Terrain Scout Transport".

This thing is meant for transporting scouts, not heavy combat.

Also, why the bloody hell is the "All Terrain Scout Transporter" a walker? They literally have hovering technology and could make transporters that fly through the air, and be heavier armored due to not having to walk.
