Mistake in PPB data?

[Wardad]

PPB is good but has these drawbacks:

1. It is expensive in terms of minerals and rads. I really adds up to a lot of maintenace.

2. It takes research to get to the PPB tree, And consumes research.

It may be better to research Shield depelters and APB.
SD trees off the shield field which you typically research anyway.
APB has twelve levels. So it would take a minimum of 1.2 years to research it.
Spending turns researching other weapons could delay the APB and SD.

Don't under estimate DUCs. They are cheap to research and pack a good punch. They are expensive when compared to APB.
