There is no such thing as a small significant change when it comes to dekans. Both of the main builds (STR and INT) are nerfed to **** because str dekan has no steroid skill (thats what dragon nail is in that post) and int dekan has no burst (thus the % hp removal addition which is also what warlocks/wizzies need) some of the other changes are just qol changes to make pve easier like moving splitter to suction so DKs can solo grind easier.
Basically without a large overhaul of their skills I dont see dekans getting any better.
