We have about 90 Backup jobs and do not perform synthetic fulls. Instead we do monthly active full backups and stagger when the full's run across the month so only 3 full backups run per day. We are backing up to a dedup appliance that backs up to AWS Glacier and we average 8 to 1 dedup.
I'm looking forward to 9.5, because the upgrades prior to 9.5 were horrific. It would take weeks to catch up after CBT reset with the upgrade. The product prior to 9.5 was definitely catered to smaller hyper-v environments.
