The need to make minions individually more meaningful is really counter-intuitive to their purpose in an encounter.
They aren't there to make the party go 'OH NOES A GOBLIN CUTTER!'
That goblin cutter does 4 damage. That's it.
However, FOUR goblin cutters do an average of 8 damage a turn on a 50% hit rate, whereas your goblin skirmisher (the equivalent of four cutters) will do an average of 6.5 damage per hit, with +1 to hit over the cutter, that's 55% X 6.5... still less than 8 damage. The equivalent level Lurker, if it has combat advantage, will do 50% X 9 damage... but the cutters will up their average by 2 to make 10 damage per turn average....
The cutters are already outdamaging other equivalent monsters, and are capable of damage spikes without crit-hit rules. That's without leaders coming in and upping their damage considerably. +2 damage to four critters is a LOT more potent than +2 damage to one.
Just because you can ignore -a- minion doesn't mean you can ignore a standard encounter with them in it. They don't need love, they got more than enough love as it is.
