not gonna say they should be easier, they are fine as they are imho (takes a very solid tank, ToV geared SK doesnt make the cut (splat really fast)), good heals and good dps.
what my concern is though they are rather considerably difficult, on a 8 hour respawn and their tear drop is only 5%?, thats worse than drake orbs in EtoV, now i know you dont want everyone running around with 2.0 but with the way luck falls you could do a full clear of WW 4-5 times and never see a tear ( thats alot of time spend for a full group). i would only mearly ask for a custom drop rate depending on the dragon ( some of the easier ones sure 5%, but some of the tougher ones that hit for over 4k dmg maybe boost them to 10-15% that way the risk vs reward stays rather steady.
also is it anyway possible to move tsiraka outside the cave? ( makes things annoying on a already tough mob)
(alternate idea about tear is add in a 35% drop (fragment or whatever), that you combine x number of them to create a tear), that way at least if you dont get enough in a full clear at least you make some progress.
