In 3rd, you added a fraction of the skill to your basic move. It was fairly useful for that.

On the topic of Reliable, I genuinely don't understand why people have some kind of issue with it. There are plenty of reasons you might want to build a character that's very skilled with one ability without being especially intelligent/strong-willed/broadly talented/etc.

It's about how the cost is assessed. Yes, you should be able to raise your activation/skill for an ability independently. I would not base that cost on the cost of the ability. It creates situations where it is a bargain for some abilities, too expensive for an ability you have lots of levels in, and disagrees with the rate you'd pay in flat costs to normally get a +1.
