hey bud, saw your thread in the mentorship subforum. in the future, you should use the simple questions, simple answers thread for questions such as those. you can find that here: http://www.smogon.com/forums/threads/ask-a-simple-question-get-a-simple-answer-sqsa.3473806/ to answer your question, you're only putting yourself at a disadvantage by using Pokemon with imperfect IVs.
