anyone else frustrated with the ridiculous amount of damage players can take from other players, while almost getting one shot by npc's?

it seems like npc's can kill you in just a couple hits, but other players are practically the terminator. earlier my friends and i were hunting a group of rouge players. they ran outside the beta area and up against a door frame so they were just barely in bounds. i managed to get up to them and in a separate door just before the teleport, then ran around the corner with a shot gun and emptied it point blank before they had a chance to fire back, however it didn't bring down a single one. i know the damage was probably spread out among them, but it is kind of ridiculous for 3 guys to take 9 shots point blank and nobody go down.
