To be fair, they wouldn't need to make a whole forum post clarifying how GG's damage works and everything if they had just said "20% of his max health" from the beginning or even put it in the description of his kit. I know they said "based" and that confused me for a while, but after seeing the test footage I assumed that they must have really meant max health = damage dealt. Some up-front clarification about what "based on" means or, again, a stipulation in his kit to clarify, would have gone a long way to avoid people feeling misled when his damage output was more lackluster in practice.
