They already have an Achievement for Level 90 in PvP. That means, future PvP-Maps will give a lot more exp then previous maps and you will be able to get this gear faster. As of now, i dont want to see a decrease of needed exp for hitting level 40. That would just be a slap into the face of everyone who spend his whole time on it. You cant get all within just one week of farming. Some stuff needs time. Deal with it.
