The wrath of God is after the trib, right after we are taken to the sea of glass mingled with fire for the wedding supper.
The stuff in the 6th seal is not wrath related, but the fear spoken at the end of the chapter is about the coming wrath, so it probably would have fit better in the 7th chapter.
Too late to change it; it would just confuse more people.
So you see some of the events of chapter 6 perhaps involved before during and after what is displayed in chapter 19?
I’d be interested in seeing how you would event time line Revelation.
