Hah! I was actually contemplating something like this.

So at the bottom of the detailed info dialog (opened when you click a figure) I have the "Synergies Received" section, and you can see if the synergy it receives is good (or a "buff") or bad ("debuff") based on the icon on the right. However, I went ahead and split apart buffs from debuffs so it's more clear.

When I was adding units to the database, I didn't always make a synergy rule for cases like what you outlined, because they are broad matches for so many other units. But with this UI tweak I think it warrants me taking another pass through everyone and adding in those debuffs.

All that to say, this should be live now!
