Ok, I'm making a second thread about this, as my first thread is a little rambling.
I've been finding that my char is a better bowman with evasion trained than archery. My problems with archery following some testing this morning would seem to be the same problems that Novice had a few months ago.
Here is one of Novice's many threads about the problem.
In that thread Jon identified a bug that made archery working a random thing. Perhaps a 'fix better' is needed?
