The change to the visual ailment stack counter on enemies is pretty awesome. I thought I read a dev comment once saying it wasn't practical to go above 15 so this is a pleasant surprise. I love DoTs in this game and I'm really excited to actually see how many poison stacks I can squeeze out of my build in-game.
It wasn't at the time. Someone had a breakthrough a couple months ago and got it working which is awesome! It's surprising how impactful knowing what stacks actually get up to is. Turns into a little minigame of how high a number of stacks you can get.
