Kind of what i wanted to say. Where in the classic trial you would sign up for another one if you wanted to see more, here you would make a new character. But 30 days is still 30 days, more than pretty much everyone out there offers, and since apparently people are already reaching the level cap less than a month after launch (according to people at mmorpg.com), in 30 days you can really see everything you want and need to see, which cant be really said about the WAR endless trial...

Its a nice idea, in theory at least.
