As nit warangal is within top nits so its closing rank will be low but your rank is more.
With such a low rank of nearly 70k, you won't get a seat in NIT warangal. It's one if the NITs with the highest cutoff. So, even if you have a reservation, it's difficult for you. You can try for any other NITs witg low cutoff.
Good Luck.
