Especially with the decreased health, DTI makes a huge difference, even now, I know people use DTI, what can those of us who don't use it do? But it does put people not using DTI at a significant disadvantage, one on one with DTI at medium distance I would say most of the time the person with DTI will win unless he's being outflanked. DTI and fleet foot are a deadly combination, moreso than anything else in the game, and basically amplifies any lag advantage.
There are two solutions to this, either ND can nerf DTI even more or people need to stop complaining and just use it. But the DTI advantage is very real and significant. I don't normally use it anymore and didn't use it last night but I'm sorely tempted to just go back to DTI because with the AK I can pepper my shots and take out someone right across the map.
