"while other fighting type pokes generally cant if ferrothorn is relaxed 252hp/252def" This is the only sentence I disagree with, everything else was brilliant, and I agree completely. Most Ferrothorn's sacrifice some Defence EVs for SDef as well, and CB Terrakion's Close Combat hits 252 HP/ 252 Def Ferrothorn for 109% damage at the very least, a sure OHKO, where unboosted Breloom's Focus Punch only has a 46% chance to OHKO. However, in most cases this will be more than enough damage because as previously stated, quite a few Ferrothorn's don't run Max Def. And btw, this is a great answer :)
