Automatic GST systems could work. However there would be a few edits id have.
Saying ready to start. I don't think this is a good idea, Given that...well if you think about it, as long as you don't say ready... you don't spar, Which trolls could use to just waste time.
Some systems will be made,
1 being a script that reads your IP to verify it isn't from a VPN, this is completely possible and lots of games have implemented this since VPN IP's have a recognizable IP.
2. Systems that kick you out of your frame rate goes to high, To stop speed hackers, Things like this was implemented in Zone so I'm sure Classic can find a way to do the same.
3. Systems that make sure the characters health goes down and isn't hackable so they don't start with over 3.0 health or doesn't go back up when it is lowered or stay the same even when hit, Which should be fairly easy to do
4. Systems in which allows the main leader to decide who to replace and with who for subs.
Automatic GST systems and concepts are completely possible, people seem to forget most if not almost every game has automatic events. They just have systems to ensure you can't hack
