Ah well, that comes up from time to time.

Actual the game is pretty slow, at least if you look at S2 and the previous versions.
Its pretty important to take the speed of your mouse and camera into account. This actual the major mistake of most people.
Also I want to mention camerafreedom, since this has a huge effect on your play-speed.
To put this in some numbers:

If you have your army bunched up as one big "unit", you need less than 60 cpm to have full control.
I speak here about the peak, where tons of things happen.
Most of time you have around 30-40 cpm

If you split your army, lets say around your allied army (This means 70% on one side and 30% on the other)
you maybe get up to 100 cpm in peaks.


Now thats nothing, thats just some nice smooth micro here and there. In TW as it is right now, units hold quite some time, they moving slow and the game itself forgive you
tons of mistakes.


Lets get back for a moment and have a look at the original STW. Now boy, that was some real speed. Id loved that speed, since you really had to work, to keep control.
I would say, that you needed at least 140-150 cpm to keep full control.


Actual the battles last quite some time, if you dont play brainless you can have skirmishes here and there and at some point you have a big clash.
Good player will have a shootout, nice maneuvering and some good movement with changing power of sides.

The speed of the game is actual the very least thing I would worry about, there are tons of real problems. Speed isnt one.

PS: To help you out at some point. Grouping, camera, shortkeys, are very important and most new player seems to not give those aspects much of attention.
