Time to Live(TTL) was never a consideration in this game by the developers, other companies have obvious solutions. But it would require a huge amount of code and testing, something Anet is obviously not interested in doing. It seems most of their efforts are towards their cash shop and living world episodes which also boost their cash shop. I give you an example, some games have implemented pvp specific stats, ie. resilience for world of warcraft, toughness for games like Rift. Gw2 has no pvp stat to mitigate pve skill damage from players. Which is why I've stayed away from pvp, its stun->dead, all in less than two seconds. Its not fun, and quite silly actually, but it'll come down to the developers to implement specific core stats for pvp that will separate it from pve.
