Saw in the last patch that the devs want to make bosses harder and legendaries less accessible. I don’t disagree with the intent, however the method that has been used is a bandaid fix at best. Giving the key a 50% drop chance is… Ok, but increasing the mob’s HP does not make them more difficult. It only makes them more tedious.
That said, I can’t think of an easy fix to this issue. I CAN however think of a solution that would work wonders both for this issue, and the overall feel of the game… It would not be a small undertaking though…
The solution I have in mind… Is to give mobs leaping and/or climbing functions. Felines could leap up to a degree and climb. Spiders should be able to skitter on walls/cielings, bears should also be able to climb as should other humanoids. Winged creatures should be able to reach players perched on pretty much anything as for elephants, have them toss a tree or something periodically to try and knock players off perches.
The problem isn’t the health, the problem is the cheese. Adding to tedium only encourages cheese.
