Vitality's loss against NaVi wasn't surprising maybe but the MOUZ loss was unexpected. Mirage is just like a nightmare for Vitality now. After losing to NaVi there they got another loss this time against MOUZ. It happened after OT again also. NaVi's loss against Cloud9 and Liquid were also unexpected for me. Mirage and Ancient were the maps consecutively in these matches and the results were the same, 14-16. Ax1Le and EliGE were the stars of these matches by the way. When s1mple doesn't carry the team NaVi really have a bigger issue with winning these days.
Navi losing to Liquid is kinda okay. Ancient really is a CT-sided map. Lots of cheeky hiding spots and rotation + retakes are quite easier because you literally have lots of places to peek from and lots of angles to play with. Even with the errors made by oSee, Navi hasn't bounced back off it. They had an explosive CT side but once the switch happened it looks like they are struggling really hard to play as T.
Also, if Simple isn't carrying, you have Perfecto stepping up sometimes. This guy is also good in lots of things, it's just that the map is the problem IMO.
