Heroic Defence Still Upgrades Units

Just relocated to Er Kit for a quite night, and thought before bed would play the heroic defence.

Glad I did, as it upgraded Kessen from lv2 to lv3. This is how I unlocked Vanguards on Tatooine to lv3 and HWK on Yavin.

So while that makes five upgrades/unlocks in 9 months, might make worth playing them, especially with trying to collect data fragments to get better equipment for troops and heroes.
