If you are running away from another guy and you are on skype or teamspeak isn't it a big advantage if you press "r" for example, ( you put /info ) on "r" and then the server information comes, and you can tell a friend which server you are and he comes and is going to sponsor you an enderpearl to exit?
I think it a perfectly fine mod, and the reason you put is illogical to me for these reasons.
1. If you know how to type you can type '/info' fast enough to not let him get you.
2. If you are too low health to risk typing how are you not too low to use an enderpearl (which deals damage.)
3. Not everyone is on skype or skyping with someone who's not in the game with them (are you telling me they'll open up skype, and call one of their friends but don't have enough time to type /info?)
4. Not everyone has friends who play MCSG, or who have many points in it.
In conclusion, your argument is very circumstantial and therefore the mod does not provide much advantage to players but is useful for certain reasons to other players (perhaps they have short fingers, or the WASD setup is uncomfortable to them.
