On the one hand it's as the most stated, they try to avoid being killed by using an EDP Bottle.
On the other hand we do not want to relog always and lose an Activity Token, or have to wait until someone gets inside to kill you.
So, the fastest way is to use an EDP bottle (except for Sinx). Now you want to tell me it's an excuse? Sorry dear, it's not.
Solution? If it's ever possible to script inside PvP room, only being able to use an EDP Bottle, if you have been not being in a battle (attacked) for at least 10 seconds (same as relogging). We will benefit from it, if it's possible to script something like that. You cannot use an EDP Bottle in a battle AND if you really just want to use an EDP Bottle to suicide to save relogging and not losing an activity token you'd have to be at least 10 seconds out of a combat. It's similar to the new @noks command.
+1 for my own solution. =]
