Great divide number of mobs

[sapper]

hi there,
noticed a lack mobs in Great Divide,
2 wolves that path near giant fort did not come by and i believe fort also had an extra 2 -3 giants in it. Mapfiend confirms my thoughts but maps came after velious so not sure what else we can use to determine it.
i play during aus time and other guy in zone at the time was not killing giants or wolves.
possible mobs trained and stuck somewhere?
wiz spires also used to be constantly criss crossed with wolves and giants.

Eastern wastes was feeling pretty empty this morning as well, took me 10 minutes of running around to find one tundra kodiak and all I saw in the meantimes was the occasional orc.

Mobs have been pretty rare in Iceglad too. :/

Western Wastes also seems a little light on the mob density, looking for some info to back it up.
