Simply put you die because you do not understand the game mechanics. Does that condone the other players actions not really, is it your fault he attacked your ship of course not, but if you chose to to put yourself in a position to lose a ship by not preparing for the threats you could face then that is your choice and you have to accept that.
I don't think you *really* know what you're talking about or have a basic grasp of math, since while a T-9 can technically equip the same 160 mio credit Shield Generator like a Cutter, it will give him - thanks to a worse shield multiplier - a maximul shield of about 550 mW, unlike the cutter, who in a similar setup has about 2500mW in shields.
The game mechanic that is supposed to "protect" that T-9 is, that no "PvPer" would actually "enjoy" "PvPing" with a T-9 (unless it's flown by 777Driver, who's the Michael Schumacher of T-9 trucking) and "Pirates" would not randomly shoot said trucking T9, since they rather extract some of that excessive cargo it's carrying.
Our dear pillocks and no-checkers now know that 4vs.1-ing a Cutter is a slightly silly endeavour, since they'll never get trough shield or hulls before he can high-wake out, so they target the T-9, who's supposed to be "protected" by "Piracy game mechanics", which make huge shields superfluous, since he could simply "buy" his way out of the situation.
Our pillocks don't care about "piracy" or "PvP" or whatnot.
So please spare me your "deep insight into game mechanics" and "how to play the game".
And I'm not really going into the finer mechanics of "spawn camping" (while the attacker is hovering around the drop-in point and only has to "connect" to one possible "victim" jumping in, the "victim" has to connect with all the players in the instance, so the probability of the attacker seeing the new player first are much higher than the new joiner having enough time to react to said interdiction, since he's still busy syncing with 10-15 other players), instancing (while RPKs can switch instances as often as they like, until they find one with mostly harmless ships, the players wanting to oppose them would need to switch in the PRKs instance, which they could just leave ...) or "hiding behind the numbers advantage" (while the agressor can simply scan the "contacts" list to look for "griefworthy" targets, the players who want to know if an RPK is in their instance literally have to target and scan every single ship in the instance) .. because that might just blow your head away.
tl;dr RPKs are lamer than a T-9
