This one’s short and sweet. At level 4 PCs get the Score Improvement AND to pick a Feat. This has propagated throughout my whole group, but the original DM that started it reasoned "I think a lot of Feats are really cool, but a lot of people aren’t comfortable passing on their first Score Improvement to pick up something situational. So they get a freebie, because I want to see what uses they come up with.
Yeah “Costs more than you think” no I think it costs about what I expected for a lossless player. DACs are a feature these days.
