It is a big change indeed. Let's test it for a while before we say it doesn't work, after all the TP change is flat across the board and does not discriminate any activity.
One of the least used systems is deliveries. Now there's the choice between paying for delivery or risk the hauling yourself, whereas before, do the run, TP safely back to capital.
Also maybe, just maybe now the population spreads more across the territory instead of being all stuck up in the capital.
Eager to test it as it is a great compromise between the instant action to hot spots of pvp, management of ships in the outposts and the whole cargo hauling, and privateering, trader routes hunting.
