pls don't make this already easy game even easier^^
Challenge is part of the fun. Githyanki encounter is hard, sure, but it's much more satisfying to win if you had to try 10 time instead of winning right aways.
Maybe the game is easy for you, but that doesn't make the game easy. I'm someone who's pretty good at crpgs and find this combat extremely difficult. Speaking of which, your statement of what's satisfying also is not universal. I tried this combat early on before it got buffed and it was beyond me. I haven't attempted the combat since. Furthermore, if I have to try any combat ten times, by the end (assuming I haven't given up entirely, which is the more likely option frankly) I'm not going to be satisfied. I'm going to be annoyed and just glad the fight is out of the way. I don't want combat challenges to be too easy, but I also play these games to experience the story first and foremost, so after a point, all a difficult combat challenge becomes to me is a roadblock to the part of the game I care the most about.
I'm not suggesting you're wrong for liking challenge or finding extreme difficulty fun, I just want you to be aware that what you find fun about these games isn't what everyone else finds fun.
