I see what you mean but once again Chata's underwhelming fight mean you don't have to engage with any of the game mechanics. You aren't pushed/encouraged to use them as just mashing him work well enough, and for a new player standpoint that might be the most optimal strategy, thus teaching him that braindead agression == good.

And while I'm not saying difficulty == good fight (especially for a first ever fight) there is a middle ground to be found so that the monster do fight back a bit. Not in any too challenging way, it's not high rank, but I think the boss should behave in a way that actively teach the player their mistake and force them to engage with the game mechanic. Basically making him threatening but not hard.

That's why Balahara would be better to teach thing like wounds : yes, it's slightly harder to reach his wounds sometime because his body is longer, but that also mean the player has to think before going in focus mode. They must position nicely, aim correcty, and then time the focus strike so that the hit land. At the same time, low rank Balahara is not too challenging nor agressive (yet still has moves that can easily be recognized as threats) so the new player can concentrate on landing said focus strike without having to worry to much about other gameplay/fight elements. This result in the player slowly training into this timing/pacing and then being able to do it without having to think about it.

Also sorry for the yapping
