Animate dead summons Ghasts / Uses wrong animation upon summoning

While the change is fun, this imbalances the spell greatly at low/mid levels.
At level 5, any cleric can summon 1-2 ghast. These RAPE anything they touch, unless their target focuses on them, or the target has low AC and/or Saves.

I'd suggest to change the spell to something like this :
Caster Level Effect
1-6 Summon 1-2 skelettons
7 Summon 1-2 ghouls
11 Summon 1-2 ghasts
15+ Summon 1 skeletton warrior

(Yes, that means it's impossible to summon ghasts in BG:EE, but ghouls are already pretty powerful as it is...)

Regarding the animation of the spell, in BG2, the animation was great (Skeletton coming out of the earth), why was this changed to the current ... kinda "meh" animation ?

Expected Behaviour : Animate Dead isn't as imbalanced as current implementation, and uses the BG2 animation upon casting.

Edit.: Should probably have posted this in an existing thread... there's like 2-3 of them lying around.

Sorry ! :D
