I'm a es wl myself. For the ones that put 20points in bind demon, fanta+curse is still one of the best options.
But I guess some people might add 15points and just bind elite.
I'm an ES lock and I bind demon with 1 base and +skills carry me to 20 for random aura
Best strat is to farm a game for cursed TZ and bind a plain white urdar from river of the flame. Keep doing that until you roll a holyfreeze aura. The white urdar turns into a unique and keeps the cursed affix across games.
even with so few points into bind demon he can still handle ubers btw. the extra points you don't use on bind demon mean you can max out hex purge and its synergies. 5 into demonic mastery for 2 demons and consume the defiler for extra magic damage
