I had my saves on Heavily protected in score with warcry on, I believe. Which was not that bad for orc IMHO. Of course, wraith, damnation, and orcish int/wis were making them a way worse but there is no way I could help it :P, you know. In general I've never had problems with my saves. I just wasn't giving people enough time to spell me down ;)

Now correct me if I am wrong, but you want to say that wither affect is NOT shown in score after it lands? I mean I thought I will see this age loss in score, hmm.
In total, I ate three withers. Two of which were bugged and fixed later on as far as I know (you know, wither with -dex AND aging affect). I still think wither should be looked at. Destroying fun like that is not right. I could do A HELL more with this char. I had new role chapter in progress, had some thought on enhancing clan/cabal policies, was planning to RP for some perks etc. And then bah! I die with 300 hours... That's just... unfair :P

Ok, I can't write much right now, I have work to do, will make my comments later.
