I understand your justification however I respectfully disagree with it. If a customer is paying for a product that includes support. The support should be absolute and conclusive. At the very minimum if the solution has been already discussed there should be a redirect to the possible resolution so support requests aren't left unanswered. The expectation of requesting support is to actually receive support in a timely manner. Percentage is a helpful justification but not condusive in a resolution in this specific concern.
Unfortunately if this is the official stance on this issue then the contact us option seems much more consistent. however, I'd prefer to use the forum option since it benefits the community as a whole but don't have the luxury of chasing answers to support concerns on a paid product.
