As far as that post limit in order for people to vote, I understand but some put it extremly high. When that's the case, it's normal the battle stays open for a long time.
There was this one battle, I think it was Parrallel against Personify (or Px or Architect whatever

) which I absolutely loved reading but unfortunately, I didn't have enough posts to vote. So I just dropped a fully explained feedback, I know they probly didn't care about it but I for one would've appreciated that if someone did same in one of my battles.
The post thing is just a protection against possible newbies who are easy manipulated to d/r or give unexplained votes but some put it too high in my opinion.
