Leave it as-is. The time-cost of earning gear upgrades is so low. I can run low-risk content (expert dungeons, hunts) and upgrade my gear to be near what raiders have... without ever really spending time on difficult content. The only "balance" we have is we build up the tomestone gear during even patches and then upgrade them (if we don't raid) in odd patches. And technically speaking, there's no limit on gear upgrades per week if you go the hunt path.

And right now, we have an unlimited supply of i720 (tomestone-equivalent) gear through trading in crafted items and uncapped tomestones.

I know, we all want things easier, but it takes away its value.
