We end up in a similar position at my company, where a story that could be told graphically in 2 or 3 chart cards end up in a single table card for easier export or quick data absorbtion.
The secret we use is color series for gain/loss, so there is a real distinction between the ups and downs, and that draws the leadership team towards the graphs. We also provide the key metrics they want in the summary of the card, so they can get the quick numbers, but also have additional visibility in the graphical data representations.
There are also several things that can be done in a beast mode to make a table card more interesting, such as adding graphics (performance icons or even bar fill). Similar to what you can do in Salesforce or Excel, if something is hosted where you can access it from Domo, you can pull the image into the table. There are several great posts about that already in the Dojo, and it was covered in the Advanced Beast Mode class at Domopalooza last year. I'll see if I can find my notes or my sample cards from the event, it was pretty neat to see my tables with a little life in them.
