But really only Lord Rah level mobs, its still one of the champs for ranking
mobs.

I had a cobra at the moment of the utility revamp, so I got a good feel
for the change. Basically they raised its offense by at least sixty or seventy
percent in pure damage numbers, and lowered the dodging ability a bit.
Regen stayed the same. You used to do just plain old poison from coil,
now its neurotoxic. But you did have to coil back then, too. Sway was new
and can help your tanking to make it almost equal to old cobra, in lieu of
biting every round, which can be worth it since bite does shit damage anyway.
