If anything is broken on Aggron (and I don't think there is), it's Rock Polish. It reaches a speed of 432, which is plenty to sweep UU, but Aggron's just too fragile Specially, and any Mach Punch in UU can ruin it. It needs far too much support to be broken on its own. But give it Screens, a reliable absorber of its weaknesses, and maybe a layer or two of Spikes, and it's gg.
Thats kinda my problem, you need to revenge kill it (which is hard enough in itself if its the RPer - 432 speed after a RP is even faster than alot of scarfers.) Also anything with Mach Punch takes ridiculous amounts of damage from anything on its set. Aggron really doesn't take as much support as you are making out and it gets plenty of free switch ins, more than you'd expect. I find Aggron easier to get into play than Rhyperior and of course you don't have to switch out of shit like Milotic which Rhyperior has problems with because you outspeed defensive versions and are 2hkoing it every time.
Aggron is versatile even though it may not seem it and the ridiculous power of Head Smash - those combined and you have a very dangerous combination.
If it Subs on the switch ? Weee you just lost your ground type counter and it gets a free Magnet Rise.
If its CB. "Good luck switching anything into it"
If its RP then as i said in my paragraph, then it can just use Head Smash on the switch then every single one of its ground type counter is in its coverage move range apart from Steelix, but even then Steelix despises Low Kicks/Aqua Tails. Then its basically free to sweep.
Its horribly difficult to deal with something like that. Even using resistances against the absurd power of Head Smash is often futile.
