New Breach Fortress Mechanics

So I was able to only complete 1 fortress before the walls around the objective were added so I started just going in to collect the chests, after they were added my build felt WAY better and I didn't fail a single one.

Since the update I'm having visual clarity problems, not being able to see the walls, and the fact that the enhanced flame destroys them SUCKS. If the available abilities get clogged up with enhanced flame, what am I supposed to do?

My build is one-shotting guardians and has no problem with pinnacle bosses, but i have to be able to strategize my position for fortresses due to the amount of enemies and my AoE being low. Not being able to see the walls well, and being forced to destroy them if I roll too many enhanced flame abilities SUCKS.

I should mention I usually have a bismuth ore activated in the map, adding to the fog and reducing visual clarity.
