Ouch, steep. I only have about 25mil credits and am still in 2/3 72s (and some of my 78s are not "optimized") so I'm looking to get in full 78s ASAP and may not have enough creds to do so. My raid group just doesn't raid very often and I have bad luck with rolls (still only have 1/6 set pieces I need, this won't help that) and I want to be ready for the 81 hunt as soon as its released.
To add to the "ouch," apparently material speculation has already begun (on The Harbinger):
MMGs were 300k they are now 400k
Isotopes were 75k they are now 90k
EEEs were 25k they are now 30k
So count on even higher prices
