Area of Effect Options

[Chev]

I am starting a new play though with Spellpack 5. The Entangle now has a an area of effect of 40' (20' in the original game). This seem too big to me. I think a smaller area of effect or not effecting the party. If a Druid can control plants why would they want to entangle they're party? I know things can only be done as a radius with the game, but think of an enemy effect only spell as one that is cast in a shape that matches where the enemies are standing.

This brings up what I have thought of as a high level Fireball spell or a Fireball spell cast at high level. Think of a Mage of great skill casting a fire ball that is not a ball, but in a shape and size needed at the time to only get enemies. How about a high level Fireball spell that would do the same damage type/amount but only effects enemies?
