Well, since it's been a while since Iados has updated, and people were
whining commenting on the difficulty of the fangos, here's a copy of their RAWs that tones them down slightly.
[CREATURE:BULLFANGO]
[DESCRIPTION:A large wild boar. Foul tempered, they will charge hunters on sight. They are aggressive and powerful, so beware! They are often hunted for their meat, which many hunters find delicious.]
[NAME:bullfango:bullfangos:bullfango] also known as "that bas***d who keep slamming me on the ground"

The only real change is to their size, but I also fixed the bug Iados mentioned (which I never would have found, btw, because I suck at this), so now they bleed to death. This unfortunately removes their potential for weapons training (before the fix, I often got my skills to legendary by lopping of their legs and eyes, then bashing them forever with badger bone weapons).
Originally all fangos, including the bulldromes, were size 800,000, the same as saltwater crocs. This kinda irked me because bulldromes are supposed to be gigantic in comparison. So I've set normal fangos to the size as camels (500,000). Bulldromes, on the other hand, have been jacked up to the size of dralthas (2,500,000) and their crazy appearance modifiers can swing them from 50% to 150% in size. Also, I messed with the pop ratios some, because I kept getting packs of 3 dromes in adventure mode.
Hopefully I'm not stepping on your toes Iados!
EDIT: Oh, fangos are located int the creature_wyvern_mountain raw.
