I liked Nightmarjoo's tips, despite the fact that the previous post asked for support information. I think most of the choices and strats were well justified.

I have been playing NS lately and was super curious as to why some people so strongly think Aghs is core. So I did some looking into it and see that it can be a great addition if properly used. I still can't see this being core on a 1/2 position NS, however in 6.85 I am not sure if 1/2 position NS is that great of a decision, there are far better heros for those positions. The reason being that 4200 gold simply just gives you flying vision - in a pub taking advantage of that vision in the mid to late game is going to be hard to coordinate, as solo ganking mid to late can get dangerous as most the time people start to group. On a 5 stack taking advantage of the vision to get a really good initiation on a group of 3 enemies etc. would make it worth. So in my mind it ends up being situational and not a core. With that said, I would think it would totally be a core on a support NS with a gem. I actually think a support NS with a gem and aghs is pretty awesome the more I think about it, I now want to go play support NS. He seems to have some great characteristics for fitting the support role: mobility, vision, easier to get last hits than other supports, tanky so can hold a gem, great skills for supporting, can do damage in team fights.
