Learning how to breed for IV's, need advice

[djtofuuz]

Hey guys, big lurker, first time poster. So I'm trying to breed a 6-perfect IV gengar but the only downside is time investment. My question is: how important are the defense and sp. def IV's? I am know I want HP speed and sp. A, but I feel like I would regret not having perfect def and sp. def if I opt to settle without them. This is for 6th generation, thank you!


I guess my question is, how important are the def and sp. def IV's for Gengar? Do I need them? Is it pointless?

Defense is always a good thing. However good it is to you (IE: do I want to spend time going for it?) is up to the individual.
