Okay so I've taken the time out of my life to point out the major flaws of this set. Let's go MASOCHISM!
-4x resistance to fighting makes it a good lucario counter
No, it is a shitty Lucario counter. +2 Extremespeed does 54.2% - 63.9% to Crobat. Meanwhile Crobat uses Brave Bird and does at least 2HKO, but with the Brave Bird recoil doing a 1/3 of damage back to itself, it pretty much just fucked itself over with Stealth Rock combined. With ESpeed doing minimum of 54%, and Brave Bird forcing Crobat to take 18% MINIMUM, you have a dead fucking Crobat since the bar minimum is that it's left with
3% health. That is absolute shit. What do you get in return? A Lucario that had its health dropped a little bit. Hardly a counter if it forces to kill itself because of it.
-Can outspeed positive base 100's
That's it? What the hell, why do I want to use a Crobat that only outspeeds Base 100's? Most of the Pokemon past a base Spe of 100 are somewhat frail. I point to Gengar, Starmie, and Azelf for examples. I want a Pokemon that can at least fight back against these guys since it's the only unique point it has vs. Gliscor.
-Can annoy opponents with Confusion
We care why? Most of the time that Confusion is ever successful is during a switch in, and usually it has to be backed with paralysis.
-Can stop weakness to rock before being hit due to high speed
Or get shut down by EQ because of it.
Damnit I wish I can use an image to describe this situation
HOW!?!
-Helps sweepers take down walls with super fang.
By possibly gimping it out of a STAB and no Taunt to back it up, meaning Walls can likely recover their health with their healing options. Fucking. Brilliant.
I'm not even going to bother with the rest. Sorry to sound rude, but come on. At least do the calcs to prove that it IS a Lucario counter.
I wish I can reject sets.
