Old man struggle

Hey guys. I am an old player. I only want to do pvp. I used to be 2300+ rdruid at wotlk but nowadays that doesnt mean anyting. Game changed and people learnt a lot. So I started to play DH on legion but not seriously. Last season I achieved to reach 1.8K on solo shuffle. But I thought it would be hard on SS to reach it this season so I went to BGB. I now struggle between 1700-1750 for 2 weeks and after a lose streak now I am 1673.

Do you think is it possible to reach 1.8k for me or it is just my limit

Edit: I forgot to mention that I struggle the most at CTF games when I am flag carrier. Any tips for DH FC in that kind of position?

Thanks
