From what we're seeing with the regen mechanism I believe SE does want to limit the item being generated,
but it creates too much idle time when compared to other classes, especially against crafters.

Making another post, perhaps another suggestion to make DoL life easier while having the above considerations:
How about making GP regen rate higher, but with a threshold of certain percentage of our current GP?

Lets take 50% as an example,
if I'm a DoL with no GP gears, my GP should be 400, within range of 0-200 GP, my GP regen up to 200 is quicker
but if I geared up to 550, my GP regen up to 225 has a higher rate.

Whatever works for SE, I really hope the idle time can be reduced bring the least impact on what they want to limit on
