Fighters have Cleave, which is just as good as Twin Strike for taking out minions.Sure strike, the fighter equivalent, is weak as is, but playable, because of class differences - it doesn't have a twin strike competitor for minion slaying goodness
That would work for the Ranger, but the Fighter needs to be careful that he remains an attractive target. Perhaps a +1 to Fort, Reflex & Will instead of AC.If you're looking for a different style improvement, have careful attack instead grant a +1 power bonus to AC/reflex.
