I think that the powers have their place for using accuracy to deliver extra additional damage which more than makes up for the lack of stat modifier damage (for example, if I was a human fighter multi-classed into rogue, I'd probably take sure strike as my third at-will just to insure my 1/encounter sneak attack always hit). IMO, the fighter is deficient in this area, but the ranger is not. However, twin strike is the awesome when you're making two attacks with roughly a 50-65% base chance of hitting, so we'd rarely see quarry damage delivered in this manner.
