Logged on today to do one of the quests as i had some free time not a dragon up as far as you can see. Couple of weeks ago, Talendor on top of a hill un-hailable. Oh yeah 1 level 115 druid in zone so i guess hunter?
Unfortunately they drop dragon wing bones and dragon fin spikes which convert to 10 of each of dragorn items. Making them a huge farm site for anybody doing tailoring. No other mobs beside raid mobs have a chance to drop them and these guys repop fast. I think the issue more is make them path back to their spot.
They repop super fast compared to a normal mob. If someone is killing them for tradeskill drops, just ask them to let you hail and get whatever task you need/need to finish before they kill them again.
I'm with Sirene_Fippy, those haughty dragons with their "small snack" insults. Snack this you scaly twerp!
