I don't think anyone is looking for a loophole in the rules. The rule itself is quite valid and should certainly be there.
....but....the enforcement of the rule in this case seems at odds with the spirit of the rule. These guys are not looking to run though one instance or exploit any mechanics. The enforcement of this rule as it currently stands is more than a bit disconcerting.
How much time does one need to stay with a guild before they can leave and not be considered guild hoppers? Is time not the question but advancement and/or loot? Example.....I formed a guild strictly to get my toons into ToV and advance. By the way the rule is being enforced here I will be considered a guild hopper if I join another guild at a later date because now I know I would like to do so in the future.
We do not need more server rules to cover this situation, just more logical enforcement. What this guy wants to do seems like an absolute non issue. I bet that if he did not post about it, nobody would have a problem with it. Maybe there is some confusion about what he wants to do? Perhaps I misunderstand it.
The ruling in this case creates far more questions than answers since it's well outside the scope of the spirit of the rule as I perceive it to be.
Understand, I am not trying to dispute a rule. The rule is perfectly fine and reasonable. However, the ruling in this case creates far more questions than answers. I have no interest in what this guy wants to do but the ruling is important to me because it may have an impact on me if I join another guild.
