There are some things about ET:QW I wouldn't just throw away. The concept itself is remarkably nice and some features could work with some proper tweaks. It's just the execution that didn't convince many people. Truth be told, had it been a f2p game, it wouldn't have been a failure.

If they manage to combine the larger scale combat and "asymmetrical teams" of QW with the amazing fluidity and simplicity of ET, they'd come up with a really nice game. I even quite like QW and really, its failure lies in the commercial strategy.

I honestly would find it pointless if they released an ET rehash game. You would only have a game which consumes more resources for nothing.
