Well, as was stated it's behind a paywall unless you have tickets stored. This ranks up there with some of the worst crossover events I've seen.
AoM veterans get the girl for nothing but free tickets and if you don't have enough you just buy her for 100 nutaku gold...money sure but a pittance unless you are a true free to play.
AB have to get the girl in AoM and level her to 4...that takes a good amount of time and effort. I can do it with ease but only because I'm a err AoM player...wouldn't really say I'm a veteran since I'm still to weak to get event girls easily lol.
AB players get the shaft and AoM get the easy girl...kind of stupid.
