50 PLD - fill in cross-class abilities or go for 60?

Foresight is a.. meh.. thing it's not really a powerful CD in any sense of the word so you could probably get away with not having it.

While Foresight by itself is nowhere near being good, it becomes quite powerful when you pair it up with Sheltron for physical tankbusters. The fact that Sheltron is only on a 30 second timer means these two "meh" CDs can become a good CD when used together instead of forcing you to use Rampart. So I would say Foresight IS mandatory on PLD.
