Right, you get one meaning feature and maybe a ribbon at level 3 then nothing else until level 7, and then nothing else until level 10, and then the campaign ends.
You don’t have to be able to use them every round, but if having them doesn’t change the way your character behaves on a round by round basis, I wouldn’t consider that a meaningfully different feel.
A 5% greater chance of randomly doing more is not my idea of a meaningful difference, nor is a 10% greater chance of success on certain checks. That’s just numbers, it has no impact whatsoever on the decision making process or the possible outcomes. It doesn’t change the way the class plays it just makes you do the same exact stuff with higher numbers.
