I know that units get most of the focus, but target selection for defenses could use a bit of a looking over as well. Targets should only be switched when the current target dies or goes out of range, as it does now, but when it re-evaluates target it could do a better job picking the one it hits. Mortars for example should prioritize the largest group possible. Obviously using a brute's bring it on will continue to force all defenses within range to target it for the duration of the ability. It probably doesn't need much work, but I'd love for mortars to start prioritizing groups of 10+ gunners over a single jugg that it can't even damage. It would even be cool if you could choose between a couple presets for the rest of the defenses (lowest hp, highest hp, highest damage, closest, furthest). You could select for each individual defense, and whenever it reevaluates target (current target dead/out of range), it uses that strategy to pick its next target.
