Guild Wars 2

Simple question – can Omega siedge golems attack walls, and how much damage they whould deal to different types of walls is they can?
Official dev response on first part would be nice.

They can attack walls. I forget how much damage they do to each specific wall type. Just do not feel the need to use 5g that way to test.

They can hit walls, they are nice in that way but almost useless if you’re rushing and taking down walls. Generally you will have alphas with your Omega, so hitting gate is better; also Fortified wall, empires rise and fall before it does.
