When kinda just messing around in the Infinarium I noticed that after casting my earth overload my running near houses still exploded them. This led to some simple tests and I noticed that it appears Overload Earth is broken. After the cast animation finishes, the dust storm only continually reapplies protection to allies. The damage portion of the dust storm(bleeds and cripples) becomes localized to your character model, essentially making you a walking condi bot for a short duration and rendering the dust storm basically useless offensively.
No other overloads seem to be bugged in this fashion.
