When we rework Nautilus...
We have to keep, and reinforce his since of mass. He weight. His immense "crash into you" feeling. But also, his depth no pun intended. His feeling of abyss, loss and sorrowful vengeance. And yes, I mean in gameplay. I fear his rework because he has one of the best thematic in the gameplay. The fear of knowing his ult is coming for you... my goodness.
Also, don't fuck up his voice...
