Im an ex RGC tournament champs in asia region and i won a lot of tournaments in this specific region with a lot of players respect my skill and i wanna give my opinion here.
Min 18 - (Minimal Suspicion/Normal) His actions can be reasoned as he just jumps to the shrine and not to dodge the bombs since he is too far from the bomb when he jumps.
Min 28 - (Highly Suspicious/Highly Skilled) I think he is fishing for Riki since he saw him for a brief moment appear in top means he got good map awareness, maybe he predict him to be in that jungle area after clearing the creeps, since he have arcane rune too also he uses dust when he saw Riki so maybe if he didnt see someone there he will just jump in the other camp since he have arcane rune, but if you just look at it normally definitely a really suspicious moment how he jumps in that exact camp when he had a choice to just farm since his mana pool isnt that high even with arcane to fish for a kill in fogs using his ult.
Min 40 - (MH) I dont have any explanation for what he did in that moment its either he is 1000% lucky or he is MH thats the only explanation there. He had a chance to just push or just b but with his mana pool he knew exactly where to go exact spot where Riki is standing no explanation needed there he definitely knew where he is.
I dont have anything against him never knew him im not from his region so im just here to give my unbiased opinion as a fellow rgc player.
