This is a suggestion to make it easier to gather HQs for mats that you outlevel.

Once you reach 100% gathering rate on a specific mat, it should be allowed to "spill over" to the HQ gather rate. For example, let's say that with your gear, you would theoretically have a 130% chance to gather a specific mat. The extra 30% should spill over to the HQ gather rate. Either the full 30% should spill over, or a portion of it should spill over to the HQ gather rate.

This would make gathering low-level HQs easier for high-level gatherers. What would be the potential issues with a system like this?
