Voting is a perk that people pay for, so unfortunately we can't just change it now. Imagine how it would feel if you had paid for something and then it was suddenly made free for everyone. As far as paid perks go, I don't think it's a bad one - it doesn't stop players without the rank from being able to play the game and it doesn't give anyone an advantage over anyone else. It isn't pay-to-win in any way, it's just a bonus feature.
Adorable profile picture, by the way!
