Aura has terrible HP, this is to offset her health regen when she’s sitting on the station. However, this makes her trash when she’s NOT on the station, which is surprisingly often. Nader, Fragger, Fletcher can really ruin an Aura.
So why not buff Aura HP to 90 or 100 but at the same time slow down healing rate ? Only healing rate for herself, teammates would heal as fast as usual. This would make her a more reliable merc, especially on offense. Yet, with slower health regen, she wouldn’t be overpowered.
