-Absolutely hate seeing healers within range of Archer Tower/Wizard, but aren't attacked because archers/wizards are trying to take down, for example, a Hero/Pekka/Golem. I know Healer ability was slightly diminished in a recent upgrade. Still very easy for successful King/Queen walks.
-Defensive AI should prioritize attacks. If my defense is trying to take down a Golem and a wizard is attacking my TH, it'd be great if they swapped to take out the wizard.
