limiting comforting to once per day is not a very good idea!

lets you get online and you're being attacked, your troops in that city have been wiped, you comfort once to raise loy and then try to rein your city. your nearest city you can rein from is 1hr 40mins away....DOH! city gone. just one example of how bad this idea is.

messing with the loyalty system because of account sharing is not something i agree with.
