TheFalcon, in all fairness, (and assuming that you are talking about accommodation allowances) I would be very surprised if it isn't the "Freshmen" who are paying, by far, the highest rates of rent - hence (maybe) the misbalance.
I fully understand why you (and, in fact, I) believe that all should receive the same rate but I can also see why EM and co would prioritise in favour of those that actually need it to pay the rent and not for new toys, etc.
At the end of the day, the accommodation allowance is clearly woefully inadequate and last years increase will very quickly evaporate to make up for it's shortcomings, along with the rampant inflation, back-door taxes (sorry, fees! definitely not taxes) etc.
