On the forums here I have seen a few claims that multiple attacks are bad mostly due to being time consuming. The other day in D&DN the Fighter and Rogue were using up a fair amount of time adding up damage from martial dice and martial bonus to damage.
Adding up 4W or whatever in 4th ed did not seem to be that much quicker than rolling 2-3 attacks and we have recently started playing 2nd ed and the dager specialist was rolling 5 atacks a round and combat there was quicker than anything in 3rd and 4th ed. Is it an edition war thing? I can understand people preferring one attack or whatever for various reasons but it takes to long doesn't seem to stack up as one of them.
