Why is Ban Appeal Least Priority Ticket?

I get it, 90% of the people who get banned will submit a ticket. Irrespective of the fact if they were cheating or not.
But what about the few who were accused wrongly?
Don't tell me admins cannot make mistakes, you are not being realistic then.
Is it fair to ban someone for as long as you wish until you finally get time to read the ticket, since its last priority, and then later find out that the ban wasn't justified? Because that is how I feel right now.
I know the ban appeal section is only entertained in the ticket section so I won't bother laying out my justifications here.
But please, its not fair to keep ban appeal at last priority given that you might have wrongly banned some people. I have submitted my ticket and I know that you won't find any proof for the reason I was banned, which is why i feel its unfair for me to wait for ticket response when I did nothing wrong.
