I'm  sorry, but everyone i trust dislikes it. I know exactly what it is cause i have it and i really want to put the tomb raider torch lights in front of your eyes for 5 minutes to see how you would feel. Your statement is ridiculous, maybe because you dont have a game that does it worse or because your eye sight is already damaged so you dont even notice it.

Still, none of it matters in front of battery life. Its the most important thing.

Eh, out of 10+ people I personally know with (a decent amount of) experience  with it they all enjoy it. Why do you try to make your opinion a fact? If you do not like it fine but quit pretending everyone who does like it is wrong.
