You are acting like I'm pulling this comparison out of thin air.
The train of thought is very simple, and easy to follow:
1. Blackouts tickrate is exposed by someone as being 10Hz.
2. Comparisons to other BR games is immediate, and it's clearly below all other BR games.
3. I can't recall a lower tickrate being used in a shooter.
4. Is there any shooter with a lower tickrate?
5. The only one that I know had an abysmal tickrate that was publicly called out for it was Splatoon 2.
6. I lookup Splatoon 2's tickrate which is apparently 16Hz.
7. I post incredulously, how a game from such a storied and universally lauded team as Treyarch (with the massive budget they were undoubtedly given) could set a new low bar for server tickrate, not just for BR games but for shooters in general, dethroning the previously known worst game in Splatoon 2.
This is not an unfair comparison.
In fact, you invite these comparisons when you are now the bottom of the barrel.
1) Actually, they exposed that it is (at least) 20Hz but drops to 10Hz towards the beginning of the game where the live player count is at its highest. I think it's slightly disingenuous that the author is spreading it at 10Hz, when clearly this is what it drops to in an extreme circumstance. It is important that it drops to 10Hz, but it is fundamentally misleading to say "the tick rate is 10Hz".
7) "not just for BR games but for shooters in general" isn't a statement that adds anything to your point.
(You are also comparing one test of a beta where changes were frequently being made, versus tests of a released game)
