adamant should really be slashed into bd. since most rotoms (read: all of them in serious play) are ev'd for jolly azu, basically all you lose is venu, which is important but not really compulsory to outspeed, and adamant lets you do stuff like ohko chomp at +6 and take down threats like latios and keldeo with less prior damage. you also lose out on winning vs max mawiles and opposing azu, but even then most mawiles aren't max speed so you can just run max and exploit them fine. the power afforded by adamant is enough for a slash.
