Though I understand people deeming KL and KL based occupations hard, I tend to disagree under respect of the KL as it was before the merge.

My first experience of KL was passing the guard room, going down, seeing a few kipestas .. and that was it. It took some time until I learnt to drag the kipesta patrol and the kipucka terminator to the rangers, understood the respawn times, learnt to evade the sheperd kincher, understood that kizoar patrol behind cattle room is agro (and kibans sometimes for unknown reasons), that kipees dislike herbies and eggs to be killed by homins and so on.

The patrols in prime egg chamber were the hardest to learn, not only several kipucka patrols, but also a kipesta patrol flying down to the southern end of egg chamber. Understanding that there were a few safe spots, and more only partially safe ones was crucial.

Now most of that complex system is gone, risks in KL are lamentably low. Sure it is ways easier to do KL occupations like larvester, scrollmaker, and medic (butcher is not much affected whatsoever). But much of the thrill and atmosphere of KL is gone, too.
