Aldaron, I agree with you almost in each set, just I like the idea to discuss with you about bulky mence (impish)
I used to run this set in the past:
216 Hp, 52 Attack, 104 Defence, 136 Speed
Impish @ Lum berry/leftovers
Moveset: Flametrowher, Roost, Dragon Dance, Dragon Claw
Basicaly, this set reach 385 HP / 319 Atk / 244 Def / 270 Spe:
those stats let you outspeed Scarf Heracross, while keeping as much defence as the old bulky-dos, with an ODD HP (5° swich in with SR up).
Also I used to run a special fire move (flametrowher/blast), because as you know, this salamence will comes in and out as many times as possible, so steel pkms will be lured in... and I think that both skarm and bronzong will still be very common...
So, what do you think about using a fire move over eartquake? maybe even Fire fang? (but you set up for done some good damage)
Regarding the speed EVs I agree with you that *could* be pointless to reach Adamant Lucario speed, because I think Jolly Lucke will be pretty common now, still, as other people say, what about some more speed evs?
Also, I think that the attack evs in my spread should be used in defence instead, but still, what do you think about the HP and Stealth rock factor?
