Did you deliberately change the red pointy bullet behavior from hard, or is hard's busted? On hard they all aim straight at you (except the first from each spawn point which flies off at random). Try playing Hard and that Misery back-to-back, I think you might find the current Hard mode is harder because the red bullets aim at you forcing you to evade far more drastically. Maybe I'm wrong, I'd have to try it in game, but that's my feeling from watching it.
Also, looks like in Misery mode stage 2 is still vastly easier than stage 1 (same as hard-mode). Honestly, Stage 2 isn't looking very misery-like. I'm pretty certain I can currently perfect stage 2, just like against the current hard Battleswarm. At first I'd say the spacing between waves of white bullets is way too generous, but maybe you just need a third attack pattern to force you to move more. Watch the 2nd stage and you see how you stay in the same 10 degree wedge the entire time? If he spit out a timed nova mine directly at you every so often, you'd have to circle around and move a lot more, which makes all the other attacks more dangerous. When you can stay still and move slow, you basically are really safe.
