I am extremely skeptical of your claim that 8-2 gets you placed the same as if you went 2-8, unless you're somewhere in bronze/low silver where you'd be placed B5 regardless. Unless you're a time traveling wizard, it's more likely you're not realizing the size of the soft resets impact, and so discrediting the impact the wins had.
e.g. you might expect to drop 1 tier, but in reality the soft reset pulled you down 1 tier and 3 divisions. Going 8-2 then made it so you went down 1 tier, and so the placements felt pointless since you ended up where you mistakenly thought you started after the reset. Yet if you went 2-8, you would've ended up going down 2 tiers potentially.
