TL;DR people seem to love black-and-white explanations devoid of all nuance, and that's silly. Ask questions, do your due diligence, don't jump to conclusions, and don't believe the first thing you hear.
After my dumb shitpost towards nazara early on in this thread I've been doing pretty much nothing but replying to people's posts when something is factually inaccurate or misleading, and more than half the time I wouldn't need to even respond if folks did a little more reading or asked around a little more.
You really like this idea of nuance but I think you're substituting shifting blame for not doing well in open to this idea of "nuance" so you can tell yourself that you're better than you are, at an IM level. Honestly this is more of a symptom of a larger problem with Muddyfudger, that it's hard to tell if he genuinely wants to improve or if he just wants to climb as fast as possible so he can have that claim to being a good player. The latter is bad because you miss out on a lot of good experience that you only get by playing at your own skill level. I remember you said early on "I will be invite in 5 seasons", and joke or not, you're not giving yourself time to genuinely improve. I think mid-high open is genuinely your best bet if you want to improve.
