http://www.youtube.com/watch?v=9VtsnhAomJs <--- I would like to draw your attention to this problem thats been going on for a while now, it's a problem that was introduced proberly around incarna expansion, the many have shrugged it off as themselves proberly being too slow, or just lag (it proberly is some sort of lag, but its constant and everyone is experienceing it... everywhere!)
you won't have noticed this if you don't deal with fast targets that try to warp away before you can catch them... ratting and mining... the issue as seen in the video occures when a fast agile frig like a double nano rifter warps away from a gate, while a 1000-1400 scan resolution hurricane with point tries to tackle it...
The lock is confirmed on server side... the guy in the video says he is yellow boxed, but the point/module does not activate before he engages warp...
I myself has experienced being the ship getting away after being yellow boxed on gates with hostiles trying to catch me, I have confirmation that everyone dealing in the same profession of catching fast ships on for an example gate camps... have experienced the same problem...
If you have not experienced this yourself, try and lock a astroid or rat, and look at how long it takes from you press F1 to your module icon shows up on the locked target... I bet you it's between 0.5 and 1 sec...
Now I am writting this here because I both petitioned it and bug reported... but the bug hunters apparently don't think its a bug... Regardless, something changed with incarna that caused this... call it a bug... call it lag... its still a problem that needs to be fixed
