Think for me, Im just kind of tired of generic circle and square rooms.
Like look at A7, we had prisons and spikes. A11 we had a steam roller boss with switches. Some Alliance raids have pads and platforms. Jump pads.
Checkered board fights like the Queen of Bozja and E4 are a step in the fight direction for me. Same with E9 and the tiles.
But nowadays, its just bland circles and squares, and drag the boss around the room. I don't mind the mechanics to much, but a change in the layout of the stage (aside from backgrounds) would be nice. Sometimes I just want to fight on a Triangle.
