I played mage the first week then i totally despised it because its over-simplified, mind numbing , strictly based on two or three cards : fireball being one of them.
Obviously there are mage decks based on freeze or based on secrets but only a few play them because they are less simplified?
What bothers me is :
you drop bellow 14-15 life points you die .Because he sits on 2x Fireball : 6 damage for 4 mana and adds some other bullshit
no need to control the board , in 2turns you can easily eat 20 +damage from direct damage. Im not even talking when you can just lay a cheap unit for 2mana that gives+ 1 spell damage or reduces cost of spells.
