If you do want a genuine answer, I'd say look at the space your team wants to take in the moment. Back site is definitely valuable to space to take generally, but A: because you walled left-side there's a fair amount of risk of someone playing behind the wall/dropping out of heaven, so that space is quite inherently risking once the wall drops in a few seconds (not to say that the wall is necessarily bad, but there's pros and cons of blocking off an area). B: is look at where your team is. Sova and Omen are miles away, and none of you, sage or reyna are particularly good at creating space on their own (esp now that you're out of flashes). Imo it would be better at this point to consolidate the space you have, wait for omen and sova to catch up, and catch anyone playing behind the wall off-guard who's expecting you to over-extend and rush onto site. At that point, you can route backsite together and clear it a lot more effectively.
Ironically, if you wanted to play like this, the one-way for backsite actually would have helped you isolate the front site angles and incrementally clear the space (though I doubt Omen was really thinking that), but just generally I think that when you're out of sync with what your team wants to do, it's going to make it harder for you to create space, and make it feel like you're getting much less support when you try to.
