Proficiency above 100

How valuable is raising your proficiency beyond 100?  Is is better than a certain amount of hitroll if it is your weapon skill?  Is it just an effective "+1" to those contested dice rolls?

Depends heavily on which skill or spell we are talking about. It is never bad to have over 100 but in some cases it makes a HUGE difference.

In weapons cases you do more damage or defend and attack more often.  If it's a main skill you use a lot it would also make a huge difference.  

I.E. Disarm for exotic warrior

Weaponcleave for zerks

Backstab for a thief holy cow!

I'd take those over a few hitroll any day.

In skills like crafting it could mean you create things you could not at 100%. May also affect chances of managing to retain materials when dismantling as a bard.

In the case of defenses it is IMO almost a must In the current environment for races that can not reach the -600AC mark. 

In the end, a famous Rabi once said, reading the Torah 100 times can in no way be compared to reading it 101 times. :)

Edit: Welcome home by the way.

Kinda repeat from the other thread, but having 100+ protects from fear/hysteria proficiency drops. That can be huge against a few higher ranked cabal and other qrace/shaman fights.
