Something has been bothering me about how the system handles opposed rolls. Basically, as your abilities scale up, the difficulties you face don't.

For example:

Say we have a Str vs Str roll. It is easier for someone with 9 Str to beat a 9 Str than it is for a 2 Str to beat a 2 Str. In both cases you are rolling against 2 challenge dice, but the Str 9 guy gets 7 more dice than the Str 2. In fact, it's easier for that Str 9 guy to take on a Str 10, (9 ability dice vs 3 challenge) than it is for the Str 2 to take on Str 1 (2 ability vs 1 challenge).

I realize that you want to be more successful as you progress, but does that mean blowing past equal level challenges? It also means that high level enemies can't really be defended against for Ability vs Ability attacks.

I've considered making the challenge dice scale based on the opposed ability. Maybe something like ability/2 round down.

It doesn't seem like an issue if everyone has abilities of 2-4, but at higher levels it gets pretty pronounced.

What do you all think?

Interesting point. The dice system in WFRP is obviously asymmetrical. Opposed rolls aren't intended to model one against one in a fair and even contest. There is always an advantage to the roller, which is, I would think, intended as part of the PC oriented ethos of the game. Although I take your point about the unevenness of the chances of success as you get better. Also, it's worth saying that the spread of PC characterisitcs is only going to go from 2 to 5, in the vast majoprity of cases, I would think.

But anyway, if you do need to match people in a contest on equal terms, with both characters performing the same sort of act, then you need to use a Competitive Check, not an Opposed Check.

You could instead of using opposed checks use competetive checks found on page 43 of the rulebook. by coincidence they use armwrestling as an example of using competetive checks.

Good gaming

Edit: oh, Monkeylite did allready mention that. But that person is right. opposed checks have limited use, and flaws. So competitive checks are you answer.
