I've played a LOT of Sage, these are some of the most prominent mistakes I see at the higher ranks and especially when I was playing at the lower ranks. I've made these mistakes myself a lot, so I put them into a guide to try and help people understand some tactics you can implement into your own Sage gameplay.
Note - After re-watching the video there are a few things I want to restate.
Off-Angles can be useful and should not always be ruled out when using your wall, getting a double usage out of the wall by walling off a choke and creating yourself an off angle can be very good.
Not only that, but if you decide to create yourself an off angle, it is smart to late peek on the wall as opposed to early peeking as it will be much less expected. You can boost your teammates over as a 5man to get a very easy suprise-attack towards site. This works very well against an opposing sage wall, you line up, and you all boost over surprising the enemy sage and usually landing you a free kill.
