Expanding on Cracked Terrain Bonus Damage for Buildings

Not a huge deal by any means, but I think its kind of interesting and realistic that buildings on certain terrain types are a bit more fragile. I noticed that buildings on cracked terrain take 25% more bonus damage, are there any other terrains that do this?

When watching things like hidden cup, I always thought that buildings on the swamp terrain should be somewhat more vulnerable, so that there is an interesting trade off between controlling the water with buildings, but there being a bit of a risk involved. I also think this should apply to buildings on ice.

Perhaps its a silly thing to focus on, but since the mechanic is in the game, I think it would be interesting to expand upon, and become perhaps become another important part of map design for tournaments. It might be small, but it could be another interesting talking point for casters when covering the new maps for a competition.
