Question about Heartsteel and low elo

I main Shen and got back to league some weeks ago, and after going through xPetu's videos I saw that the ideal build was Hollow Radiance + DMP, also saw that Heartsteel's WR was inflated and all, since then I began to run with that but then I remembered I'm not xPetu and I'm a bronze peasant so I thought, should I just run Heartseel? I'm very low elo so my team is unrealiable and I enemy team is equally as bad so I can reliably farm stacks and stuff, but maybe I'm missing something.
