I think you have correctly identified what makes your new mechanical keyboard different from your previous keyboard, but instead of calling it 'higher actuation point' you referred to it as 'higher actuation force'. So what you are feeling is a higher actuation point coupled with
lower actuation force. In other words, you don't have to press as hard or as far for each stroke.
This is precisely the difference you are feeling. And by the same token this is one of the major advantages of mechanical keyboards over rubber dome keyboards.
With your blue switches, the actuation point is as you said higher up - exactly half way. Full travel is 4mm yet the key registers at exactly 2mm depth. With your previous keyboard the key would only register once you had fully depressed the key. That's why it feels kind of sensitive. But once you get used to it, you will be able to type faster as once you feel the bump and hear the click you can move on to the next letter and thus become faster and faster.
Having said that, the secret to typing on mechanical keyboards is perhaps counter-intuitive from your point of view - it is to key 'confidently', that is with 'short, sharp, and quick' strokes. You don't need to pound the board into submission, but by the same token, you don't use long, careful, ponderous strokes. You just do it! Good luck and let us know how it goes but I'm sure you'll be loving it in no time
