So ArenaNet devoted programming and resources to ensure that a “determined” potentially abusive player could not receive this achievement and in doing so inconvenienced thousands of players who just want to play the game?
Just the opposite, really. I didn’t implement this particular achievement, so I can’t really go into detail on the the specifics, or speculate on future plans, but the current system is a simple brute force solution to keep people from trying to cheat death by zoning/disconnecting/etc.
