As mentioned, the game in that video although cool is nowhere close to FE ... I went through all the current MMO's out there and nothing comes close except for two factors... 1 - more than 4 people play them .. and 2 - the games have a future.
If they have to do a rollback to fix this dupe version wise, and we have to start again, so be it ... I'd actually quite enjoy starting from the ground up again. Sure I'd miss all my current toons, but lets face it they're almost useless/gone in their current state anyway unless a miracle happens. My only worry is that even if we roll back to a working version .... version 1.x.z .... we'd end up being stuck with that version as there is no real dev team with access to the code base anymore. I think we'd also be missing the vision of the original team that made the game so unique in the first place even if we had it, and Gamersfirst would just turn the game into a generic cash cow.
