Suggestion - Black/Whitelist for Battlespells

[calmon]

Example from one of my mp games:

After scripting my pretender (4E/4F) with Summon Earthpower, Phoenix Power, Flame Bolt, Flame Bolt, Flame Bolt (i was fighting niefel giants) and 'cast spells' in battle turn 6 he started to cast the level 0 Spells Fire Flies and Flying shards. Fatigue was below 20. The spreading level 0 spells kills mainly my own troops, the enemy giants didn't notice anything. I don't know why not 1 flame bolt or something equal was cast by ai, it costs the nearly same fatigue and works a way better then the level 0 spells against fire susceptible giants.
Even the stupiest battle ai should be able to choose a spell at random. This is even better then to choose the worst possible spell!

After some Fire Flies/Flying Shard battle rounds later my army rout and my pretender flees with a very low fatigue value. Maybe i'm the 4721st person who say this but: thats just stupid!
