Honestly with the lack of server population, 2.5k maps provided a good amount of PvP but it wasn't too PvP focused, with the addition of 3-3.5km maps all we've gotten is more build locations and less people leaving their base, nobody roams anymore even on max pop queued servers it's hard to find PvP
Back a few years ago, 2.5km maps mostly dominated the map size, you could get away with playing a 20 pop and still get a good wipe, whether your playing more relaxed or casual you could still find PvP...
In today's era of crust on a 20 pop you'll find no PvP even if you counter large, cargo, labs, Brad etc, people prioritise loot over an actual good gameplay experience
