That's properly shit if the unique uniforms for Superman and West are gone. The others literally don't matter. Not sure who needs to hear this, but a generic polo that says 'Storm Coaster' or 'Green Lantern' is not a themed uniform.
I'll also say, I've HATED the teal trimmed shirts for a long time, along with the dark navy shorts. Worst uniform by a mile, so while i still despise the Generic branding, I much prefer the plain black with the bright shorts. The old black on black looks like something that only a cleaner or a warehouse person should have worn, and the teal didn't really add anything. If the trim was in other colours, and it was park/department specific it could work, but not a fan of just the teal for everyone. Plain black is significantly better for my taste. Still not what I'd go with, but I prefer it.
As for non park branding, welcome aboard the bandwagon! I've been driving this thing since about 2010.
