Fast turns the game into an FPS. That's okay for people who want to play Sins in FPS mode, but not for everyone... because Normal is like normal was, but we have no slightly faster mode.
Let me explain why this is important. The fast mode in 1.09 allows things to happen faster. Whoever can manage things the fastest wins, which is a fine style of playing if you're here to hone keyboarding and mousing skills, which is fine if you're trying to improve your keyboarding or mousing skills... but many of us don't need to. Many of us also likes our detailed empire version that took almost an hour if on a small map, and hour or two if on a medium, and a couple hours or more if on a large.
The Normal on the 1.09 beta is too slow, and the Fast is too fast. If you want to introduce a FPS speed, please introduce a new selection of speed. Do not just take away our fast RTS style speed and replace it with a fast FPS level speed. This doesn't mean RTS speeds are inferior, it just means people have to pay attention to more detail every second to win... while at higher speeds, things go so fast that it's about how much detail you actually manage to manage makes you win.
So if you're going to span out the max and/or min speeds, don't take away the origional speeds and replace them, add more selections.
