Everytime you die and you're on your way back to your corpse, just ready yourself for the worst. Expect that you're going to get full looted. At some point before you hit 20, try to think of a list of basic regear items that will leave you decently geared to get back into pk or ranking. If you can train yourself to get into a routine regear for your characters losing that sweet set won't seem so bad. It's just part of the game, some people do it, some don't. Expect it every time and then you won't be so frustrated or dissapointed, ready your regear list and just hop back into it.
