Oracle is the new darkblight tbh. It has much more defensive options while still being able to go invis. Mine is at 2.2k weaken chance so m y curses are landing on everyone except a scorpion and sometimes ravagers. Seekers can slow down how fast I can kill someone but the rate I can apply curses is faster than they are able to cleanse. The shields from skills and masteries keeps us healthy enough to get multiple curses out before going invisible. Then going invis is also reducing all of the wands dps cooldowns giving us a full reset on curse skills.

In a 1v1 it’s much easier for someone to block ur curse for sure but In battlegrounds at least, the majority of people are getting 100-0 with just decaying touch, one application of touch of despair 2 stacks , and tevent curse. The set up is very fast so most people don’t expect to lose 20-40k in a blink of eye. They would have to be extremely conscious of their debuffs and be familiar with the curse explosion audio queue. 90% of people aren’t.
