Every time I decide to play Ast, I find a thread that destroys my enthusiasm.

No I haven't. Because I am self thought. I like to learn things by doing it myself instead off reading up guides.

Different people, different way of learning and there is nothing wrong with that!

There's nothing wrong with that. However, there is something wrong with you not noticing your MP going faster when you use LA and you not noticing that Refresh is an MP/TP thing when the tooltips for the Ewer and the Spire also say that the cards add a refresh effect, just like LA. If you're not going to read up guides, at least read up the Actions and Traits menu.
