Heh. On second thoughts, a ~15% increase compared to the others does seem a little bit..harsh. To me it seems to of been psychologically set like that, to make the people think of a big increase when its not much really.
Though if this is linked to capacity issues or whatever technical reason behind it then i have no quarms
(ftr, not a rant, happy with the increase, it just seems a tad out of proportion with the others)
