This crossed my mind as well, however I think the reduction is the correct thing to do.
Why the reduction: They costed everyone a lot of credits during a time frame and they are trying to allow them a chance to recoop some of their losses.
Forum reaction: Will people qq when prices go up, probably, but you could give everyone of the forums a free pizza and a very vocal minority would find some reason to qq about it.
What? Just a free pizza? But. but. I don't *like* pizza. What about meeeeeeee....
I do expect to hear a bunch of 'my repairs went up 100%!!!' when 2.0 is released. Hopefully, the mods will just close and remove those threads immediately.
