I'm not intending to be rude in any of this, I'm sorry if it came across that way. But the reality is that a number of people (not the majority, but a number of people) have complained about that ambush for example, and in almost all cases it usually turned out that they were missing something basic: wasting items, not using the moves with the right timing, not knowing there was a heal skill you could use out of combat etc. Similarly, your trouble with the Mahir fight was, genuinely, down to you not understanding it. That's fine, it's designed to be a little difficult to "solve" to motivate players to take the jobs instead, but it is still the case that you were failing to solve it.
You're coming to me with a number of things and saying "this sucks, change it." Which is fine, and even good to some degree because often I agree, and especially over the first few months after release I was able to fine-tune a lot based on feedback. In this case I disagree, but I'm trying to give some insight into why, and some information that make make the game easier for you, rather than just saying "No."
To be clear, being annoyed by the Daze attack is entirely reasonable, and it's somewhat down to taste whether you find it a fun extension of the "being powerless" theming, or just obnoxious. There was some debate about that after release, and I did revisit and carefully consider exactly how the mechanic was working (It's actually deliberately manually restricted, it used to go off MORE). But at this point, I'm not in a position to be reworking significant parts of the battle mechanics: most changes to GT now will be either really serious bugs and/or very simple, easy adjustments that I somehow missed.
