Donut-shaped boss areas

Some boss areas such as Sharzul’s chamber, Rashalga’s den, and the end of Stonerend Quarry have a donut-shaped layout. Was this a deliberate design choice to limit cheesing? Or was it possibly a subconscious expression of reverence for Crate’s food of choice? Donuts go well with all that beer…

I mean, if anything, donut shaped arenas enable far more cheesing than they prevent, due to enabling ranged to kite the bosses around in a circle without any issue. Toughest boss arena I’ve ever dealt with was the EoR boss arena, which is more of a dumbbell shape.

There are a few maps with certain designs. Like Smuggler’s Basic looks like a heart and the Queen’s Lair area looks like an angry face.
