C5,
You are not alone. A lot of people didn't like the drama die espeically in conjunction with the difficulty scale. There were some skills and situations that essentially mean that no one if thier right might would have picked up. For example, if taking off and landing with a Flight Vest is a Challenging (TN10) skill test, character most characters need a 4-5 rating just to survive a shot flight. And the flight vest was made to replace the more difficult to use rocket boots (in which case flight boots should be banned and ownership of which should be considered a sign of someone comtemplating suicide).
Unfortuantely, CODA's TN's aren't much better. With the TN to use a flight vest a 15 (and a 2d6+skill+stat mod) characters need a 8 skill (6 plus speciality) to even consider putting on a flight vest. A character with a 12 skill (plus Rocket Boot speciality) in Operate Vehicle, the MAX skill rating, still has a 27% chance of blowing a skill roll. And that's just for basic operations. Try something fancy and forget it.
