Whether it is space or ground combat, a very very common quirk is the response time from when you fire and when you fire.
Confusing? Yep that is exactly what it is.
Here's a few examples.
In space combat with target shields up:
<Hit hotkey to fire torpedoes>
Response time: instant.
In space combat when "Target shields have failed." <Hit hotkey to fire torpedoes>
Response time: 3 seconds. (more than enough time for target to do a 180 degree turn and place a fully charged shield in the way.)
I am on a 12 meg connections with 10-30 ms latency. So I am really really confused why the lead time is so varied.
Same thing occurs in ground combat..fortunately expose times are bit longer than 3 seconds.
