I will not play IC because of this.
So when is it OK to take something from someone that earned what they have? If I am killing NPCs and earning TV stones, why can you steal them from me?
Seriously, what skill does it take to hide until a boss nearly kills a player, then jump out and one hit the player and take 80% their TVS? Zero, nada, no skill at all.
On top of this point, they don't take a modest amount, they take nearly everything.
On top of that, if you want to play in IC you have to go through Cyrodiil. This causes an imbalance in the PVP areas because the player slots taken are from the total allotment for a faction in any given PVP campaign.
It is for this reason and several others that I personally am losing interest in playing ESO. Its just not fun to play ATM.
