sage is bad on icebox?

for a long time sage has been regarded as an icebox staple. But is that justified? Was doing some data analysis and found something quite interesting: in the 246 times in Stage 3 VCT that a team with sage played a team without sage (on icebox), the non-sage-team won 154 and the sage-team only won 92. That's a 63% winrate for the team without sage, and this is a fairly large dataset, so I don't think it's a sample size issue. In addition, I know sage isn't meant to be fragging, but every single other agent averages more frags on this map, even util agents like Killjoy, Viper and Sova. Even sage herself averages more frags than this on every other map except breeze.

What's going on here?

wasn't she important because of the wallbangable box on b site?

main reason people played sage was so they can plant on B site without being wallbanged through the default box. Now that the Box is made of thic metal it is no longer wallbang-able so no worry of getting a plant without getting odin sprayed.

i play sage on icebox and i get around 13 aces in one game , she's good :)

because sage is just an easy solution, if u want to play it without sage u need super good game understanding and cordination, wich rather better teams on that map have therefore they win. also sage gets no kills because she is only there for planting on attack

I guess it is just a comfort pick for players who plays duelist on other maps so that teams need to use it.
