AdjeReading through these I'm pretty sure most of these are fine but stuff like less obnoxious Pyro flame particles would be up for debate cause you could argue it's intended game design (although not great game design). Kinda similar like how you can't use that mod that hides props & bushes to remove clutter on ETF2L.
There is probably a middle ground to be had where stuff like that is not inside of the pack?
I suppose. But I think the highlight of that pack are the Flamethrower changes. I think most people can agree that the default flame particles are horrendous. Whereas removing props & bushes is something completely different.
Edit: And besides, orange flames have been in the game for a long time (pre-JI). So it isn't something completely different to Valve's intended design.
