I don't mean to drive the topic into the ground so maybe I'm missing an obvious angle here, but would you mind elaborating on why it's such a big deal for the rules manager to just change the rule of creature types to allow them on non-creatures instead of jumping through hoops having to make the Tribal supertype? Seems like the less complex solution would've been to just snap his fingers in the same way you guys did to eliminate mana burn.
I’ll use a metaphor. I have a handyman come to my house. I point at a switch on a wall and say I want it over there instead. Simple, I think, just move it.
But the handyman understands that in order to have the switch in the new location, he needs to get electricity to that new location and the house isn’t currently wired for that.
He also can tell that the place I want to put the switch has plumbing behind it which would severely complicate him doing what you ask.
He’ll say to me that he can’t do it, but what he means is it would require so much aggravation and time and money that it’s not feasibly possible. What i think of as a simple request is actually a giant undertaking.
This isn’t a case where the Rules Manager can “just do it”.
