Well the good news is when the game is fully released they will likely have various modes of difficulty, such as Story mode. So you can simply have a combat experience that meets with your level of expertise and not get stressed about encounters.
No need to be patronizing and make it an issue of "expertise." The issue is that Larian's kind of "challenge" in combat is not really challenging but rather just repetition, tedium, aggravation, and stupidity. And whereas all those things may be great fun for you and some others, there are those of us for whom it is decidedly not fun.
I largely agree with the OP. And I am yet to see anyone actually posting a thoughtful and well-reasoned counter-post, as opposed to just attacking or flaming the OP.
Edit: Okay, credit to @fylimar's last post for being a thoughtful and helpful post.
