I used to hate Extremity... the eye-gouging colour, the low-gravity dynamic, the rat-run of narrow canyons. I used to hate it so much I'd log off every time it popped up in the map rotation.
But now, it's one of my favourite maps. I'm not sure why I changed my mind... perhaps the variety that it offers vs the other maps, the way it turns poptarters into popfloaters, the clever "hot v cold" dynamics, and the number of rocketpack BAs I get to swat along the way.
It was a useful lesson for me in how an aspect of game can seem bad at first, but once you get used to it, can actually be quite interesting.
So, I salute the devs for the low-grav hot-cold concept, and this map in general.
