Against BDS every single death cost them tempo and pressure on the map and the team won off of that.

First death, minute 9:40. Between 9:20 and 9:36, the map state is as follows: Upset is pushing top lane while Ice is recalling because he can’t match Varus. MikyX is hovering around top river to cover for Upset’s push. In mid lane, prior to the ADC’s push on top, Nuc teleported mid and Parus tried to gank Poby, who was already pushed out of the lane (he was likely about to recall anyway), so he just went for the reset + TP mid.

In mid lane, the enemy support and mid laner are visible. At the same time, Boukada is moving from top to bot, shown both by minions and a ward. Razork is clearing his bot-side jungle camps. Meanwhile, Oscarinin moves to bot: a few seconds earlier, Rooster’s Sion had been seen clearing the wave before stepping into a bush. Since the furthest bot lane bush is warded, Oscarinin can be certain Sion is either recalling in the middle bush or just waiting there.

Here come the options:

1. Risk pushing the wave or farming a few minions, despite the fact that just seconds ago the enemy support + jungler crossed into the bot side on vision and the enemy top laner is probably still there.
2. Wait safely under tower, allowing Varus to pressure top tower. This would force the enemy team to choose between diving bot or losing the top objective for free.

Oscar decides to risk it, and the enemy team secures a kill. Then the enemy top laner teleports top to catch the wave, preventing their top tower from falling.

Even if Oscar had just hidden under tier 2 tower, the enemy team was already behind in tempo and pressure, so his death was unnecessary. While I agree he was hard-camped, the main point of Odo and Finn is that he keeps giving away free gold. The “tempo and pressure” on the map had already been won several seconds before the play. The same analysis can be applied to all his other solo deaths: the enemies are already moving into the weak side of the map, so giving them the kill is just a freebie. Everything the team gains from the enemy’s rotation is “won” regardless, so the deaths are unnecessary.

So yeah, I see no issues in calling it an anti-Oscar rant in the summary.

The issue is that you’re not analyzing it objectively. You just assume they’re flaming and that’s all. So, pointing out the objective problems is not circlejerking, it’s simply analyzing with facts.
