Some notes on the Misty Mountains:

The density of Giants in all locations in which there are giants, especially Iorbar, is far too high.

Giants are an excellent candidate for the application of directional inductions, such as those found in Moria. These large creatures would not be able to 'turn on a dime' to target a clever player dodging their blows. This would also drastically reduce the monotony of 'giant-farming.'

The Crag-hawks or hendrevail are also much too dense, as are the bears just prior to Gabilzan.

Worms and snowbeasts are also guilty of unnatural density on the slopes leading up to Helegrod.

These areas need to adopt a more Forochel-like approach in their creature spawning patterns.
