Sorry to hear about your loss but I'm curious why you took such a big risk betting on Nigma? Meanwhile, as far as I know, TS is one of the teams that relies on playing speed.
What I know before I quit following Dota 2, TS was one of the teams that was feared at that time or maybe I was too far behind regarding the latest information?
I'd assume it's because of the group stage format being a bo1, they could catch Team Spirit off guard, and with those odds, it's understandable to go for the risky play.
You're not that far behind when it comes to Team Spirit and the current competitive scene, they're still one of the scariest teams together with the other two(Team Falcons and Xtreme Gaming).
BTW, regarding the Riyadh Masters tournament there is an interesting first match between G2.IG vs Entity. What do you think, does Entity still have a chance of winning faster in the first match? I think yes
I'd give them a high probability of getting one map, most teams aim for a draw and avoid losing 0-2.
