they would never expect something that can completely shut down their ship and kill them before they realize what's happening, because other players' ship has superpowers, which takes eternity to grind for.
Early on in the game a four second burst of laser fire from a Viper, a couple volleys of missiles, a single alpha from a railgun equipped ApsX, or just colliding once with one of the larger ships around (or a stationary object), could send an player who put in dozens of hours of effort into getting that Eagle MkII straight to the rebuy screen.
Nothing seemed surprising with TTKs on this level to anyone who had played many air or space combat games (anywhere on the simulator-arcade spectrum) featuring fighteresque craft.
Plus, as with recent example with Sir Gankalot dude, it shows pretty well that if you come across wing of gankers that know what they are doing, you have absolutely zero chance to escape, and nothing or no one can help you, no matter how your ship is built or how experienced you are.
This is a terrible example, because Ganksalot was screwing around and trying to make for a good show by fighting when he was supposed to be running, and is leading you to completely erroneous conclusions.
If he was actually trying to make it from point A to B, without getting shot down, he'd:
-Not have been on a preannounced/static route (limiting escape options and allowing reliable ambushes to be set).
-Not been streaming without a delay (likewise).
-Sent his wing ahead so he wasn't flying blindly into danger (a mitigation for the above).
-Had his wing proactively interdict people before he arrived (as is this).
-Not tried to scoop fuel after the first jump while people were clearly waiting for him and just dropped out of SC to prepare the next jump (even an expert pilot cannot reliably get to a low wake before a high wake is ready to go, outside of nearly perfect starting positioning).
-Not have deployed hardpoints to fight after being interdicted (waste of time spent assessing targets for engagement rather than following his own best practice escape advice).
Doing any one of those differently would likely have meant escape.
At every step prior to his CMDR being shot down very early on, he chose what he thought would make for an interesting stream, rather than an uneventful one.
