Blazes need to be harder

Blazes are too easy to kill. These seem to be fire demons or something. I would like to see them be tougher. 

a) Improved accuracy. I can stand still and the blaze will miss 5/6 shots. 

b) fire charges/balls deal more damage

C) if the fireballs are blocked by a shield, the damage is prevented but you still catch on fire. 

d) improved AI, they are kinda dumb.

e) have them fire more shots and lessen the cool down. *The blaze misses all shots* I can get 3 or 4 hits before it can shoot again.

I just feel that these Mobs should be a lot harder to defeat. They are essential to the game's progression and should be tougher.

p.s. Ghasts need the old fireball, LOTS of damage and light everything on fire.
