If I used up everything in a fight you basically cannot re-gather blood through exsanguiate fast enough to get back on your feet.

most fights require 1 or 2 skins, tough fights can require 3-8. If you are toting around an enslave you have a pretty big restriction on your mobility which hinders your ability to control what fights you get in.

You basically need blood and/or slave for the overwhelming majority of encounters you see in the upper levels and if you run out and even just 1 person harasses you to keep you from restocking with oily skins you are basically ineefective (solo) for the rest of the login.

I also think that orcs are look disproportionally good at hero because of a couple of very high attention ones in the last few years and I suspect that 1 person accounts for like 70% of the chiefs in that time. I honestly think they just roll, hero, play to con death, roll another orc. How else do you explain the years of having orc chiefs who never participate in the forums, always play morning hours, and play out the same build over and over. Now he does lose the throne from time to time, but man he/she has had it a long long time
