So stupid me discoverd that its not worth training forretresses special defence and I thought since I have a forretress with offensive personalety maybe I should train its attack and not special defence
reminder :
forretress-impish nature
a little quick temperd
ev'd in -252 defence 252 special defence 4 attack
Actually, on Forretress, The Best EVs are: 252 HP, 200 DEF, 40 Attack, 16 Special Defense. So yes, change them.
