So this is less paid beta test, more an opportunity to support Digital Extremes and demonstrate interest in this new title. Granted, when DE did this last time, it was essentially a hail mary to keep the studio from going broke, and now they have the backing of Tencent and such to fund their efforts. I'm still going to buy in anyway since I missed out on Warframe's founder program and I want to support a home grown developer.

As for the combat, I can at the very least say that it's getting better. I was in the original test very early on, more or less when they were just letting folks run the build that they initially showed off at Tennocon (the Warframe convention), and it was extremely clunky. It's no Arkham combat system, but I trust DE well enough to make it work, and it is better now, even if it still has a good ways to go last I played it over the summer.
