I've been giving some thought to reactions in CODA lately.
As things stand, Reactions are damn near useless in opposed tests. Unless you roll really well or put a lot of advancement into them, or both, you don't stand a chance in hell of successfully resisting another's skill.
Let's take an example. Spock (Mind meld +10, Psi Modifier +0) tries to Mind meld with an unwilling James Kirk (Willpower +4). Even if Spock rolls the minimum possible, Kirk will need to roll a 9 or higher to resist. And if Spock gets an average roll (7), Kirk needs to roll a whopping 14 (minimum!) to resist.
My suggestion would be to change how reactions are calculated. Instead of taking the better modifier of the two attributes listed for each reaction, average the two and use the score, not the modifier.
For example, Kirk by the current system has Quickness +3 (+2 Agl mod, +1 from Fit), Savvy +3 (Prs mod), Stamina +3 (+2 Vit or Str mod, +1 from Fit) and Willpower +4 (+2 Vit mod, +2 from advancement). With the suggested changes, he would have Quickness +10, Savvy +10, Stamina +11 and Willpower +11.
The new values would literally even the playing ground when trying to resist Spock's Mind Meld.
On the con side, though, This makes it really easy to resist the effects of phaser stun. When you have a +8 or 9 and the TN for Light Stun is 9, it makes it a little too easy (even with the TN modifier from a successful reaction test). However, in my (admitedly cursory) examination of tyhe rules, that's the only place I've found a set TN for a Reaction test. Maybe we could raise those numbers as well (Maybe 10/15/20 or even 15/20/25 vs. 9/12/15)?
What do you guys think?
