If at all possible, I would still consider doing something about all those sub-queries. In many cases they wind up in a place where they can't be optimized by the DB engine. See if there's any way to convert even one of the sub-queries into a simple join it may result in huge time savings, especially if you can index some of the tables involved.

This has been fixed. The issue was not with the sql but with the query rule that was calling the view. Slight changes were made to the view, however.

Yeah I think it would be helpful to know your use full case - what data are you displaying and how are you showing it? Often in cases like this there are a lot of possible ways to fix the issue, and many of the possible fixes don't even involve database tuning at all.

Before we would want to begin tuning your SQL, we would want to confirm how your Tempo report is utilizing paging - are you returning say 10 or 15 rows, or trying to return all rows in the DB, etc?
