Though the d2 bugs me too I still much prefer the random bonus and the MRQ progression over fixed bonuses.

A fixed bonus rapidly sets a minimum damage threshold that proves quite lethal - especially when used with hit locations.

A creature with a +3 damage bonus is pretty much goint to always take out an average persons arm on every hit, even with a relatively weak damage attack (say 1d4). If the same creature instead had a +1d6 damage bonus the average damage done will be slightly higher, bit there is still a chance that it will do only a 2 point wound.

The opposite holds true on the max damage side. That d4+3 damage is never going to do more than 7 points, were it a d6 bonus it could do 10 (and hence do some real damage to a heavily armored foe). Though this 'max threshold' doesn't bother me as much as the high minumum damage value.
