It's a rare game that I don't max out miner 69er. While I sometimes play with friends, I more often play solo, so mining becomes a necessity. Given that, and the fact that I always have my pick-axe with me, lockpicks become a waste of inventory space and thus, the perk becomes a waste of points. The only reason I could ever see speccing into lockpicking is if you a) don't want to do any mining, AND b) have someone else to do the mining for you. Yes, there are alternative means to obtain cobblestone and cement, but no efficient alternatives present themselves for the acquisition of nitrate, coal, oil shale or lead, which is why both A and B must be true to pass on miner69er.
