From my point of view:
If you have a team of Challenger players vs a team of low diamond, wouldn't it be "better" to ban their comfort picks no matter if they're meta or not?
For example, I Wouldn't be surprised if a Gold team banned the comfort picks of an Iron team they were going against, even if those picks aren't meta in those roles, forcing them onto picks that they aren't as comfortable with.
Would people say it would be disrespectful if it was an all male low diamond team which happened to be all support mains if the same bans were made?
AlSO. If you watch the VOD the entire team was laughing at the bans, so unless laughing means "I am upset and offended" in Russia, they didn't seem to feel offended or disrespected.
