I am a High Sec miner and my point of view is through that lens. The Orca is pointless since indy core locks it in place with no panic module and it only carries enough fuel to boost for 45 minutes. If the Porpoise is locked on grid by the indy core it will be just as pointless as the Orca but at a cheaper price.
FYI- High ore mining for a orca is about 2-3M isk per hour in ship that cost 1.8B isk fitted. Mining will never cover the loss of a single orca. The risk vs reward is very off for high sec players now.
Please keep put up the good fight against CCP to make the game better for everyone.
