I might be able to chime in on the gameplay in a day or two to truly see what's up. I see the post is illiciting a negative response, but I'm not entirely sure it's warranted before even watching gameplay.
Do make sure to adjust your approach when seeking advice though. If you feel you need to preface a vod review with details about your teams apparent lack of cooperation or pulse, then perhaps the chosen vod isn't good material for you to learn from. You would ideally want to detach the emotions from the gameplay and ask objectively for improvements you can make. Venting can distract yourself from asking for help the right way.
Some better vods to review would likely be close losses or wins, or games where you're the one who ultimately feels you didn't understand what to do and tried your hardest to little success alongside a team that visibly did the same. Those types of games can highlight the most errors with positioning, timing, cooldown and ult usage, counters and adaptation.
If I may be pedantic, the right way to look at solo queue is you're the common factor in every match you play. But you can still be matched with and against 4 stacks at this elo in my experience, so some games are not true solo queue. They can go either way from hard to influence factors. Your goal is to be over 50% winrate, and to try your best to improve it.
Even then you must face the reality that 40-50 out of 100 games will be losses of varying intensity and reasons, even if you are playing well. That's a lot of losing while climbing, it happens!
Anyway, I'll take a look eventually, try to make it more clear that you mean well, and to everyone else, please make it clear you mean well when trying to critique someones approach. It may deserve benefit of the doubt and not be that deep.
As a preemptive note. When I review this knowing the person feels they deserve a rank higher than plat, I expect to see very good mechanics and quick reactions to opportunities, good awareness.
