Sadly, I am the ONLY ONE that has come forth to say that I actually would find it to be a little bit of fun every once in a while. I mean yeah, there is the issue of lots of servers that could POSSIBLY turn on 24/7 turbo mode, but think of how crazy this could actually be. Personally, I understand the problem this could bring, but you have to also think of the attention it might get and diversity of gameplay. Even if you didn't make it SUPER SPEED just having a server side option of 1 that would make it so you can't change the speed to whatever you want would be cool.
To be completely honest, I don't think 3/4 of the server would change over to turbo mode considering that a lot of the servers are owned by beta testers or people that aren't just turbo mode enthusiasts. Maybe make it so that you can't have 24/7 turbo mode? What about making it only capable of having 3 rounds of it at a time or something? I guess though that nobody on the team is interested so this might just be a post in vein......
on the bright side, you might not get sniped across the map as easy because you can escape fire and the person faster....just a thought.
