I used to play a lot of MTTs, however, the long "late registrations" just makes the MTT's last even longer ~ last one I played took over 12 hours. I am not interested in being tied up that long...
I agree 15 mins late registration is long enough.
poker sites just keep registration times open longer so they can get more "buy in fees".
So, if I join a MTT with 432 players, thinking that it won't take all night, it may turn into over 1000 players before that registration closes. Makes it pretty impossible to plan my time.
That is why I have to play sit n go games, instead of MTT. So, I would really like Bovada to limit those late registration times!
