AP is easy to come by so not really.
But you did give me a idea...
How about decreasing the AP cost to 100, keeping the current hpd cost, having the reset set to 24 hours and then having the option to use additional AP and hpd to decrease the time? Each additional 100 ap and 1k hpd you pay will decrease the time to completion by 1 hours.
That's a good idea, I'm thinking maybe several options to select when you start the IP Change task:
24h, no AP cost
20h, 600 AP
16h, 1500 AP
12h, 2500 AP
6h, 4500 AP
Might stimulate usage of AP a bit, and if you need a fast IP Change you pay with AP for it... sounds reasonable.
but the 1k HPD cost stays the same, so even newbie players can use it.
