As much as I hate slaughtershit, I can, at the very least, respect the amount of time and effort they put into creating these fuckhuge levels, even if they could have been used in a much better way.
What I cannot and will not ever tolerate is speedmapping. Nothing good has ever come from it. It is a bastardization of art, it is the lazy moron's way of getting attention from a bunch of freaks, who don't even like Doom. What the hell does speedmapping ever do for a mapper? Wow, you can draw a bunch of shapes really fast, without thinking, and then you copy & paste those designs all across the map, after which you throw monsters all over the place in the belief that it works somehow, before "the time runs out".
There is no love, no thought, no self-reflection and no finesse. Speedmappers usually don't even craft something with the music in mind. Do you know how important it is for your map's gameplay to exactly sync up with the music during the first two minutes? No, of course you speedmappers don't, you're trying to shit out an abomination within the next 4 hours, while bitching about your daily life problems & libtard politics to your Twitch viewers.
