I'm fine with it, I'll prob buy the Sleipnir Mount only or something else I like. Many others MMO's sell items to customize your gear and blablabla, for example, Blade&Soul or even the "loved" World of Warcraft.

But the first step was made.
They said it won't be pay to win, but I remember Yoshi-P saying this game wont be p2p forever. If they start selling items to buffs to increase XP, +1 roll or lockout removals, I'll really be worried and will have reasons to cry.
