This EA will last a LOOOOOONG time, I bet easy 2 years, so I do hope 2-3 months down the road they will unlock level 5 and maybe even do us a solid and make some sort of Arena or some such so we can slam some random NPC encounters while we wait for actual release for 2 years.
What, two years until the full release?!! Gosh, at that point I wonder if they should do away with the concept of a "full release" and just make all the content incrementally released. Yes, yes ... perpetual dwelling within the mists of unknowing over several years.
