I hate Mages. Mages are seriously killing my enjoyment of this game. Losing against other classes at least I know either my deck was built poorly or I made a mistake somewhere. Losing against a Mage I know I lost because the class, even taking into consideration the nerfs to frost spells and Pyroblast, has been getting far too much special treatment by the developers.
Not only do they have an absolutely overpowered hero power (dealing 1 damage for 2 mana is far more powerful than it sounds), every Mage deck contains each of the following cards guaranteed:
Why? Because these cards are seriously the best card in the game hands-down. Mages will apologetically humble-brag about how bad their class has it but, without any hyperbole here, you are bad at this game if you cannot do well playing a Mage. While most games I play are in constructed, every time I play an Arena run I pick Mage (when possible) solely for the raw power the class has.
Once I get Lotheb, he is going into every deck I build even if it doesn't make any sense. Perhaps in the future we will have more counters to Mage cheese so the listed cards can remain the same and maybe Fireblast will be toned down or replaced but for now Mages are anti-fun incarnate.
