At the end of the day if voting for yourself truly puts a person over then fine. The battles are good fill free to vote for yourself if you can vote for yourself by all means. Internal votes for yourself always have to be present, that's with everything in life. The goal is to transcend those votes, and make them irrelevant people can vote for themselves all day but if it doesn't put them over then it's null in void regardless. I find that these competitions are bigger than just "Battling" because at the end of the day a person can win 100 battles but if they don't build positive relationships with those around them then it's over for them. Not because they didn't win a battle but because it truly takes good networking to do anything of note. Being a great producer with no relationships is the equivalent to being a great producer and not being able to turn your passion into your career, and that's what really hurts.If you vote for yourself and that decided the victor them it shouldn't count since the other person just votes for themselves and it's a wash anyway.
So make those votes irrelevant because at the end of the day it isn't about the "Battle" sure it feels great to win, but it's temporary.
