Thing is, it´s always a two-edged sword to duplicate information.
If you have, say, the unit HPs on the card text and on the HQ list, and on a patch said HPs are modified, you gotta remember to change both the database of HQ info and the card; if you don´t, you create more confusion that what you solve.
Therefore... yup, fully agree that unit info on the cards would be great, but it does imply some effort both to do it AND to keep it updated. And since one of the staple of online games is that they are continually chaging, update is not something to be overlooked.
At any rate, for Los Señores Devos to decide.
