It never became not useful. So yes it is "still" useful.
But I think you are trying to say, is that you think it is effective. And the answer to that is depends. It does stagger anyone who hits you( but bosses) and gives you a lot of defense, but it makes you move like a s*** brick house. --- XBL: XOsamaBinHidnX
I rely on mobility with my character so for me Iron Flesh is only effective on rare occasions. But the few times I did use it I noticed that it have me a LOT more defense so I imagine if you're more of a tank that it could be a pretty viable part of your strategy. --- I boosted some of my trophies. Please, judge me about it.
I used to use it all the time before it got nerfed after the first big patch. Its still useful, just not as useful against bosses. --- PSN ID: radiatedduck the most wonderful thing about radiatedducks, is IM THE ONLY ONE!!!
