You’re asking why a glass cannon can hit you like a truck when you can turn around and do the same thing to them. As a guardian you can directly counter a thief with proper use of Blind, Aegis, Focus Shield, Invulnerability, Retaliation, Counter Pressure (Burst), Crowd Control (Pull, Immobilize), Large amounts of burning, AoE, etc. If I had to choose the most direct counter to my class it would be a DPS Guardian.
As for other classes such as Elementalists, Mesmers, etc. They put out more damage more often, along with providing more team utility.
If you’re complaining about backstab you’re playing poorly and deserve to die.
