I agree. I know photoshop, illustrator and I tried Xd, but indesign is by far the fastest tool to layout for web (and print offcourse). Guides, grids, styles etc are so useful, but adobe doesn't have to reinvent the wheel in XD.
The export asset is great in XD, the prototype function too, but please adobe, keep it simple and give XD the opportunity to import .indd directly into XD.
Photoshop is for photo and pixels, illustrator for vectors and indesign for layout. Let XD be a tool for asset exports and prototype - preview and sharing. + make it possible to make breakpoints (in indesign or in XD) and link the content + make a pixel perfect export to simple css guidelines for the developer (font sizes, fonts, line-heights, margins & paddings)
Thanks Justin. I have voted on that topic and left a little info.
