I noticed on the recently posted analysis for Mega-Lopunny that the leftover 4 EVs were placed in Defense, rather than HP. Could someone explain why this is? I've been led to believe that when using leftover EVs from a given spread, it's usually best to place them into HP rather than Defenses. Is this more of a situational rule, or is there a specific reason for 4 Def M-Lopunny?
This post might help. Last 4 EVs for offensive Pokes should almost never be put into HP, to reduce residual damage, so better it gets put into one of the defenses.
