WARNING

me, I hate it as well.  Ive mentioned it before as well. 

All you have to do is be patient
2 seconds isn't that long time for wait.

The system is in place to stop flood attacking.
(Though maybe he can decrease it to 1 second, but you gotta wait answer from CK for that)

No, 2 seconds is fast enough, surely? It used to be about 4, then 3, now its 2.

I can't go any lower than that. If I remove the limit, every player will be limited only by their actual ping, meaning some people near the server will be able to attack every 20ms.

Not only is this unacceptable for the server, it is unfair for people with slower connections/greater latency due to distance. There's also an element of gameplay here, because it makes attacking a calculable thing (i.e. you can determine roughly how long it takes to attack for most players by just multiplying the attacks by 2 seconds).

You have to move around to find the next enemy to attack anyway, and the time that takes is absorbed by the 2 second throttle. Most people won't see it much. People who attack incredibly fast will see it, but there's not much I can do about that.

The only solution I can think of, is to make the error page a bit less of a dead end. Perhaps putting a button to go back, or try the attack again, and make it focus automatically, so you can just press RETURN to continue on.

I hardly ever actually see the error, I press Q too fast. I do usually try to guess when the time is up. But every now and then I get the error, I didn't say I wanted it lowered or gone, just complaining about how much it drives me crazy when I don't count correctly, or I get a little lag and run into it. 

i never gets it cause i has sucky computer lol. and yeah, removing it / lowering it to 1sec would be too much of an advantage to certain people with faster connection&PC
