If you can do something without EUD then you should. It would be like destroying your own map if you used EUD where you don't need it.

It's like using EUD to detect the amount of minerals players have instead of just using the Accumulate condition. It just sounds stupid to me.
It requires you to do more work, doesn't work for Mac users, and becomes unplayable after a patch.

How did this topic even come to be?

You're doing it wrong.
