Dark and Poison buff means it's a fantastic offensive typing this gen, everything that resists it gets hit for SE by Ground or Fighting, so take your pick.
Secondly is Poison/Dark is still a ridiculously good defensive typing very little gets a good hit on it, it can even survive quite a lot of strong ground attacks.
There is also the crit mechanics being reworked means 50% of the time Drapion is hitting you with a 2.25x damage attack (equal to LO at +2) WITH STAB with nothing more than a Scope Lens.
Keep in mind even if you don't go that route Knock Off got that huge buff so you no longer have to juggle Crunch and Knock Off in the same set giving a new moveslot to defensive builds.
