Now,

 

All of us forgotten realms and baldurs gate veterans got a taste of the RAW POWER that spell triggers and contingencies gave to Mages.

 

These abilities are a tremendous amount of fun and when they worked you actually got an adrenaline hit from sitting at your computer screen.

 

What are people's thoughts of obsidian intruding these powers for Mages?

Yes please.

The designers at Obsidian are up for contingencies, they just require a ton of work to put in the game.  It's no accident they didn't make it in the BG series until BG II.
