Did you see his games at all?It comes down to what you think is more likely a) it was rigged or b) the admins randomly got a top ~3% draw for viewership.
RE: Hera vs Yo. From just HC3 and NAC3, it's clear Hera outperformed Yo. Hera lost only 3 series, none to anyone but Viper (8-3). Yo went 5-4 (mistakenly said 4-4 before) and lost 2x to Viper, once to Hera and once to Max. Yo barely got out of R1 in HC3 vs Villese. Add in all the success Hera had in the small tournaments (even against a non-tryhard Viper), Hera is the clear #2.
Viper said his series vs Yo was the toughest in a while, but he's also said he threw the one game he lost to Yo (G2) hard (which I agree with, he had a 26 vil lead in mid castle age and just didn't make skirms vs conqs for some reason.). G1 was an easy Viper win, got the lame off and snowballed from there, he even threw in a forward to hide his identity (paraphrasing his words there). G3 Viper was never behind, and the game was basically over at the ~23 minute mark when Yo was 2:36 later to castle age. G4 Viper messed up his dark/early feudal age (a bit more idle time, did a late MatA that did nothing, lost water with 1 dock vs 2). Yo was way ahead and threw, I'm not sure that's a compliment to Yo. Overall, hardest series in a while might be a bit of a misremembrance.
In nac3 you could see something was wrong with mr yo vs villese, his face, he was tired or had something(they said he didn't sleep) you could clearly see that, same like tatoh facing hera, his eyeballs were about to pop out from his face, he was so sick.
If you go back and watch the games btw Yo vs viper you would see that despite viper wins, the games are close and he pushes a lot the snake, unlike the fans hero.
You could check mr yo aoe2 career, he has been the most consistent opponent viper has to face in finals, the only exception was when he was inactive while lierey was shining.
In conclusion there are a lot of players with similar skills and the snake above everyone, there was a tournament about who was the number 2 about 6 months ago or less, hera lost in there, last ranked matches mr yo destroyed hera, i would like to see a show match btw those 2, since tatoh seems to be a bit lost, he is not even close to his own level 4-5 months ago, same with mbl, he doesn't seem motivated since he is studying, lierey well i lost hope with that boy, he is now like jordan someone that was above all other players but after a long break he couldn't recover.
Then you have themax, nicov and daut around the same level, probably dogao close to them, then laaaan, accm, bact, villese and f1re, vivi is only good for ranked matches but terrible at tournaments.
One or two tournaments doesn't tell the whole story, hera needs to consistently defeat mr yo, mbl and tatoh to claim that #2 and to be honest i think he could due tatoh and mbl losing interest and shape, mr yo is only active for tournaments but most of the times he plays less than the rest.
