Remember with A2, while you're in worse shape than 98 if your opponents calls with 55, you're in better shape when your opponent calls with KK, KQ and similar hands.

People fear domination probably a bit too much: while you apparently have half as many outs, in reality your equity is about 3/4 what would be with "live cards", plus there's a smaller probability your opponent holds a dominating hand given you hold one of the cards.
