YAYAY. My favorite Pokemon is getting some love

The thing about Lucario is this. If Lucario outspeeds use and abuse Close Combat or the coverage move of your choice (Crunch+Ice Punch). Otherwise, due to this fast-paced metagame, you will find yourself doing a lot of +2 ExtremeSpeeding. Due to Lucario's high attack stat after a +2, factoring in his Life Orb and ES high base power, he will be doing significant damage to weakened Pokemon. For example, Landorus with some prior damage will fall to +2 ES. (+2 252+ Atk Life Orb Lucario ExtremeSpeed vs. 0 HP / 0 Def Landorus: 242-285 (75.86 - 89.34%) -- guaranteed 2HKO). Lucario is honestly meant to break walls such as Skarmory or Hippowdon with +2 Close Combats or to come in Late-Game and clean with +2 ES.
Now the thing on the Special Set. It would work. If the meta had more Vacuum Wave weak Pokemon. Like I mentioned earlier, Lucario relies heavily on Priority Moves because of his low base 90 speed. If Lucario were faster, NP would definitely see WAY more usage. But that isn't the case. However we still have Agility Set that could work....late game. For example, a +0 Adamant Life Orb Ice Punch will smash Landorus. The scenario would look like this: You scare something out with Lucario. Set up an Agility as they run to Lando. Ice Punch :)
Now this is obviously not always going to happen, but with massive Entry Hazard Support,and a weakened team, maybe Agility could work?
Here are some calcs against some high-usage Pokemon:
252+ Atk Life Orb Lucario Ice Punch vs. 252 HP / 184+ Def Gliscor: 270-322 (76.27 - 90.96%) -- 25% chance to OHKO after Stealth Rock.
252+ Atk Life Orb Lucario Crunch vs. 248 HP / 216+ Def Jellicent: 205-244 (50.86 - 60.54%) -- guaranteed 2HKO after Stealth Rock
252+ Atk Life Orb Lucario Crunch vs. 252 HP / 36 Def Jellicent: 283-335 (70.04 - 82.92%) -- guaranteed 2HKO after Stealth Rock
252+ Atk Life Orb Lucario Crunch vs. 192 HP / 64 Def Reuniclus: 260-307 (63.56 - 75.06%) -- guaranteed 2HKO
252+ Atk Life Orb Lucario Close Combat vs. 252 HP / 0 Def Politoed: 316-372 (82.29 - 96.87%) -- 62.5% chance to OHKO after Stealth Rock
252+ Atk Life Orb Lucario Ice Punch vs. 0 HP / 0 Def Tornadus-T: 250-296 (83.61 - 98.99%) -- guaranteed OHKO after Stealth Rock
252+ Atk Life Orb Lucario Close Combat vs. 4 HP / 0 Def Terrakion: 546-642 (168.51 - 198.14%) -- guaranteed OHKO
252+ Atk Life Orb Lucario Close Combat vs. 4 HP / 0 Def Politoed: 316-372 (98.13 - 115.52%) -- guaranteed OHKO after Stealth Rock
So basically. After an Agility, Lucario can outspeed and KO all of these Pokemon with some support. Some like Tornadus-T,Scarfed Politoed, Terrakion are easily handled by Lucario. Others like Reuniclus and Jellicent need some prior damage and a lot of ER Hazards.
My final words: (kinda of a tl;dr kinda thing here):
Lucario has a much more dominant Physical Set than Special. Agility Lucario is very viable in this metagame as it has effectiveness and a surprise factor. Albeit, it struggles more with walls and needs much more support in terms of wallbreaking and Entry Hazards.
To Gamefreak:
Just give the poor Wolf Speed Boost aight?
