70 disc is fairly low. Well built/equipped str based toon should really have 85+.
Yeah I know it's low, which is why I'm remaking the toon. Ended up with less skill points than I needed, so no UMD above ~18 ranks or so. Else i'd probably have ~90 disc.
@ klixon: I believe I had about 70 AC with 50% conceal at the time.
