That's because those changes aren't necessary. Especially not as a priority.
Different people can have different definitions of necessary. Are those changes strictly necessary, well, no. However, they are absolutely things which can be IMPROVED upon.
Since September, there has been a
thread for Talent suggestions, which is 5 pages long. I think maybe one (1) new Talent has been added to the game, which I find discouraging given that the game is still ostensibly scheduled for release in mid-2017.
There is a new patch once every 2 months, and the Talent selection is underwhelming, with a lot of poor or questionable Talents, and there has been zero indication that Larian has any interest in changing that.
So yes, I will definitely be trying out the awesome new Polymorphing and Summoning which they have been working on for a long time, but the clock is ticking ever closer to release, so I am also going to try to bring some other things to their attention as well. That okay with you?
