They can't attack her without making themselves vulnerable, and even if they're dancing in and out of cover, Pharah can wear them down with splash damage, while they have to re-target her constantly after losing line of sight, which is advantage: Pharah.
Soldier 76 and McCree are considered "counters" because they can shoot back at her, unlike heroes like Reaper, but an equally-skilled Pharah has at least a reasonable shot of killing them both before they can kill her, or just dropping out of sight when they try and take her out.
Really, we just need more hitscan heroes with some range. Orisa will help, as will New Bastion.
