I can’t find record of real drop rate percentages on items, besides some stat counters for your own stuff, ( Like what the add Mob Info 2 Does ) or on thot but there does seem to be a pattern.
If I’m the only one farming for an item – the drop rate increases – Hence why I can churn out 16 Netherweb Spider Silks from mobs In Terokkar Forest near Shatt in 40 min one day when I’m not competing.. ( Tuesdays before shutdown seem to be the best farming for things like that as there are less people on) and then struggle to get 6 in an hour on another day when I’m competing. ( even considering that i would be killing less mob due to the competition thats still painful )
It seems to work the same for blues and Epics patterns - I get my best drops at 2am in the morning – yeah for holis soon! so I can actually play at 2am
I always try and Farm at least one Primal shadow ( and for the cloth that drops and odd green) when I do the Nagrand goggle quest, going round the crystal in a circle, but every man and his dog ( or pet) seems to have the same idea. When people go round that circle they all go the same direction. If you really want to upset them, go the opposite way – you pick up quick spawned mobs and you get to the ’meaty’ mobs before they can – and then the cycle repeats itself..
