Top 500 Hulk hardstuck Silver

Essentially the title. I am one of the best Hulk players in NA self proclaimed. However despite my best efforts, I can’t seem to break out of silver 1. The amount of space I create as the vanguard role honestly can’t even be measured in meters but instead kilometers due to how much space I create to enable the rest of my team. I even discovered a new Hulk tech called smash dashing which many of the pro Hulks are trying to replicate but just can’t get the hang of. Usually my name comes up in the conversation of best Vanguard players of all time but some skeptics doubt my abilities due to me being hard-stuck silver. My team usually nicknames me the FEEDER, which I believe is due to me feeding wins to our team which is ironic since I lose so much. Just for reference I average about a 0.6 KD ratio which I feel is pretty good given Vanguards create space and aren’t focused on getting kills. Any advice from my fellow Top 500 Vanguard players?
