Easy to understant... wall is too expensive drop price to 100$
I really need to explain ?
More recent changes to sage make the wall worth the price drop, however in the mean time I would recommend trying to find new and inventive ways to use sage walls that can easily lead to 2+ kills, which means you get 400+ credits in the next round. I would highly recommend looking at the youtuber Grim (https://www.youtube.com/channel/UCWphjEePrzIrRA5mwcOt_4Q) to try and use sage walls. Get inventive with it and I'm sure you can find more ways to make this ability worth the 400 credits.
