Should I reroll for Vark?

Just to start off; I know the general consensus is that rerolling is a huge waste of time and to just play the game. However I'm coming back to the game solely for varka and there's only 10 days left; I know he's not meta or anything but TWO CLAYMORES. Thats just sick af to me. Is it realistic to grind out enough primos to guarantee pulling him in the next 10 days, or should I put in the time sink to re-roll if I'm only really interested in getting Varka?
