The base monthly price in USD for EVE is $14.95/m. Annual subscription takes that down to $10.95/m at a total price of $131.40. Google says those are, respectively, 84.68/m, or 62.02/m at 744.28 annually.
Compared to WoW: USD prices are $14.99/m, or $12.99/m for a 6 month rate (annual cost $155.88), the base USD cost is cheaper for EVE.
The actual difference sounds like Blizzard (a much larger company than CCP) is selling direct to the Brazilian market with locally priced offerings. CCP doesn’t sell directly to nearly as many markets, so you are getting strictly currency-converted pricing. The conversion rate is not set by CCP. The only way for them to affect this would be to build an entire pricing structure for Brazil - which they do not yet have a localization for that would support this kind of change. It’s also not exactly cheap for them to reprice for any given region.
So while I feel for you, this isn’t something CCP can quickly or efficiently change, and it may not be a financially viable move for them anyway depending on their player population in the region.
