Yep, I hope M+ will receive a buff to be roughly on par with raiding.
Even at best, the vault item levels cannot be as high as the drops from the current tier’s end boss item level drops (for keys that is). So you have to do fated mythic Denathrius to have a shot at 311 gear for instance and keys can offer 304 at best - and valor upgrades stop at 298.
If we could upgrade to 304, that would be a boon. It’s a grind either way, while raiders spend 3 or 4 hours in one sitting to finish their gearing, we’d just do smaller sessions and then farm valor which either way, consumes quite some time.
