It is there. You can change the file system as you want. See left of the marked area in the screenshot (the screenshot is reused from another thread). Why not sit down and have a real look at the partitioner and its options?
It appears that you didn’t find what you want at the first click and now are completely opposed to have a closer look at all the options. Yes the partitioner is different to the old YaST one. But no, it is not bad.
