/practice
can be enabled only in a team, and only if all team members "agree" to that by typing /practice
as well - there's no really way to destroy team play as using /rescue
in practice mode would teleport the player to last platform he was standing on, and so everywhere in between two platforms there is still needed help of teammate - only if whole team died there is sense in using the rescue option. For people going in solo teams it wouldn't change a thing. (edited)
