I would be in for short rest being anything 15+ minutes, BUT ONLY 1 between encounters (even if it is longer than 15 minutes) to avoid 4th edition syndrome of healing mutliple times or using encounter utilities etc...between every 5 minutes
I never played fourth edition, but my question would be why would you need to take more than 1 rest between encounters? Is there something someone could do over and over again? Either way you would have to have an encounter before you could rest from one in my book so no problems there.
Rest Option:
Yeah: 1
Nay: 3
Amendment 1:
