Actually, the Kultorask is a strength. It will take down a frigate fleet better than any other titan because unlike other titans such as the Eradica with Chastic Burst, the Ragnarov with its shotgun, or Vorastra with The Maw, it can use the health of enemy ships to heal itself and by extension, it's allies while also disabling all enemy ships. In the event that something goes wrong, you can simply press Nano Leech -> Gravity Pulse -> Dissever and drain, disable, and nuke all enemy frigates and capitals in range.
Once again, I completely agree with you. The focus of it is the fleet. So it fits its role quite well.
The titans
TEC Loyalists - Defense
TEC Rebels - Offense
Advent Loyalists - Really no clue
Advent Rebels - Sacrifice
Vasari Loyalists - Mobile base
Vasari Rebels - Destruction of large squishy fleets
I believe this is correct for now, please correct me if I am wrong
