Neither is raising and lowering skill gains every time someone asks instead of looking at it from the perspective of usefulness/profit in hunting and time required.
I don't think that the time that it takes needs to be changed. It's long, but there's a huge, huge, huge, benefit.

I'm not so sure about the success percent. I haven't seen a lot of problems with success when I've tried it. Harder monsters will have a lower percentage to be provoked since they drop better loot. There should be a challenge to hunting harder monsters and if you can just provoke all the dragons into one big dragon pile, the 'strong' dragon is suddenly a pushover.
