After leveling to Physical Level (PL) 12, I noticed something strange. At PL11 my stats looked like this:
When I dinged to PL12 and opened up my allotment menu I had 8 points to distribute. This is where it got interesting. In order for me to level strength by 1 I needed to spend two points. All other skills required only 1 point to raise them by one level. Could this be SE's way of making sure we don't just level one stat? I didn't notice if this was occurring from PL1, so I assume this is a recent thing.
