Porcupines have been deadly for many years, like even in the old days they were and since they boosted monster dmg over time in various ways, they've stayed one of the most dangerous mob types in the game if you're clearing fast. Map affixes I don't think they did anything specifically lately, they did fix ground stuff but that was several years ago, they changed how shock is applied too but don't remember when. You might just be seeing stacked damage modifiers and such, they did change some things to monsters a while back(was more than a year ago though I thought). Just make sure you have shock immunity or don't step in the bad(but it's a pain to avoid).
