Performance issue and Lost Experience

Ok GGG, great game first of all, but your performance issue that you are having really sucks. I will give you an example that just happened to me:

Temple of Chaos. Went through 3 times and retrieved the 3 pieces needed for the boss encounter at the end. Went in to the encounter and started it. Literally put down 3 ballista's, and then the screen froze. I get the Grinding Gears Symbol, then the message "you have failed, you have died"

Not only did I lose the encounter and all of the loot. I lost the three pieces to start the encounter. AND I LOST 10% EXPERIENCE!!!!!

This is twice today I have died because of your "Performance Issue". So no loot from the encounters and I lost 20% experience.

I understand the penalty of dying in the game should be imposed on players. But when the character dies because of your "Performance Issue", you should reimburse that which was lost. Make some kind of compensation to the players.

This is very frustrating!!!! Makes me not want to play your game and give your product bad reviews because of such a horrible game issue.
