Thieves are not supposed to be good at killing things. This is because they are unambiguously the absolute best at theft. Doing more to make thieves competitive at anything else is not a good idea. In fact, making them worse at certain levels at doing things other than theft is - arguably - a good idea, and dropping thief points available at lower levels would accomplish this.

You post a lot about wanting thieves and shifters power increased, which is a bit funny because those are seemingly your favorite classes to play. And they both share the trait of being unambiguously best at filling their niche while also having significant limitations in other niches.
