The achievements are fun to get throughout, but we really need updated kill counts and new achievements to reflect those of us who have been here a while and to also give us a reason...for coming back to those zones.
I don't expect retro-attribution, but for example, I already got the 30 Harrowstorm achievement and I was surprised there was not a 50, 100, 200, etc. Same goes with dragon killing in North and South Els. Increase the counts on those significantly and with new achievement titles.
In the same manner as seeing a Master Crafter title, a nod of respect to somebody who's taken out 1000 HS's ("Dark Heart Harrowstorm Master") , and somebody who has killed over 1000 dragons ("Dragon Dominator").
Updating achievement numbers and titles for the basic Dolmens would be great, too.
P.S. With future DLCs, consider adding 50, 100, 200, 500, 1000, etc. achievements with exotic name titles.
