Yes, it's pretty bad how warriors and shamans counter fear, a problem originating form Vanilla's raid bosses imo.
Let's not forget: There are classes that counter stuns, roots, snares, or polymorphs, too.
With shamans getting stun totem and paladins AoE-blind priest's psychic scream isn't that unique anymore… still, it's strong! It's AoE, easy to target, instant, has a short CD, doesn't break on light damage, doesn't remove dots, moves people away (not always in the intended direction ), works against targets in stealth, works reliable against most classes…
