...Which is fine by me. I hate getting stuck and having to look up a guide to tell me what I missed so one of my guys (or gals) will indeed have that skill maxed or near maxed.
Well, if that's all it's going to be, then I don't think it should require an entire talent point just to use something of such marginal and optional utility. I think lockpicks would be better if they were more like the identifying glass for identifying items with the loremaster ability. You can still manage their overuse with lock levels, chances for breaking, or number of uses, but I think one single use no matter what is rather prohibitive.
