15:04:12.094 Stormcaller Blast Tank's Defensive Systems hits Kemenotic for 843 kinetic damage, causing 843 threat.
That is on 8 man, i doubt it would be hitting for over 2k on 16 man, so it is still very little amount of damage as long as you're topped off and fly back into a shield and not in the middle of no where.
Yeah i think you are right here. No one should even be using the tanks to get to their shields. It's not very hard to walk off the tank and get to your shield within the (10?) seconds defensive systems is being cast.
