Please keep in mind that the exchange rates are reviewed every 3 months by Cryptic and adjusted where needed. We're getting more C-Points now for our Euros than a year ago. Where 100 CP used to cost 1.20 Euros they cost only 1 Euro now.
Cryptic already indicated that it's not feasible for them to review the exchange rates on a daily basis. Personally I don't think we have anything to complain about when it comes to this. Americans get their C-points for more Dollars than we pay Euros, so it's not a 1:1 exchange rate. Never was either.
