I am definitely against the XP/Sp loss, it's pointless. Why should you be penalized because you traveled from a R1 camp to a R10 camp just to have some IT aggroing mob chase you down and kill you, very quickly in fact. Because of the placement of high level aggressive mobs in lowbie areas it increases the risk of death too often.

Lets see, there was a Sand Peiste (level 45-50 mob) that was camping lowbies right outside the gate of Uldah many times when a lowbie was going to a rank 1 camp. So if he got eaten (happened twice to me because mob saw me before he spawned on my screen) the player should be penalized? No thanks, that is just plain stupid.

How about the aggressive high level orge that has appeared closed to Horizon camp? So a level 15-25 lowbie is going happily to do their leves and shrek's evil red ogre-cousin kills them? Again, that just doesn't make sense. And don't forget those giant ants that are aggressive too and appear in the middle of doing your leve and at times block your mission.

Plain and simple, no exp or sp loss penalty. You get punished enough by other things in the game.
