If you have steam, you can map most controllers,(without any extra software) I will say its not that great, but it can get the job done. I'm sure once Mindark make official support for controllers it will be a better exp.
I would have to disagree, I use an xbox style controller from amazon and using a software I've been able to map it flawlessly. That combined with the ingame key binding interface makes it possible to do anything in eu with the same settings if done well.
I fear mindark implementing their own system would ruin the fluidity of what I have going on, should it interfere with the software im using.
