Addons that should not exist
The comunity always has those addons that are hated more than others, 3 blink nurse for example. But what addons you especifically hate?
I personally dislike pinhead Iridescent Lament Configuration, because it is super opressive against solo survivors and won't make a big difference against a SWF. Not mentioning that pinhead's power make soloq hell even worse, because you can't coordinate who is going to the box.
From the survivor side, both insta-heals are unhealthy.
