An Idea for the Endgame Collapse

I absolutely loves this game and a big reason for this is because of the "masquerade" feeling, what I mean by this is similar to Dark Souls. Everyone knows it's a game but even the core mechanics of the game "stay in character" The matches aren't called matches, they're a trial that an entity has created. The picture I'm trying to paint is how awesome the Endgame Collapse is when the very trial underneath you shakes and leaves glowing marks on the ground. Now I could live if this never happens but I feel the Endgame Collapse could change the game enough to where the term "Endgame Collapse" could mean something dangerous: for both sides. For starters I feel like the Endgame Collapse should begin the moment the last generator is fixed, the timer will tick down, but a lot slower, so you could probably work with some other perks or even new ones. while the timer ticks down, I think if the map "broke down" or maybe let it change tiles... maybe even make some tiles very unsafe, after all its the Endgame Collapse. so the idea would look and change the game in a completely different way. The concept of this game is beautiful and I'll always respect developers who care enough about their game to add lore and instead of "you unlock potential in ones aura reading ability" they could've added something generic like "you can see the killer" I love this kind of development and it really makes me feel like I'm playing a sick game for an entity's approval. I don't want to sound like I'm complaining about the Endgame Collapse, It's OK for where it's at, but the collapse ends fast.. it just doesn't feel like a Collapse for all the glowing marks and the rumbling if it ends quickly.
