I'm sure they are hesitant to add a new level. A new level of collector would actually place a pretty sizable *burden* on the economy for many weeks or even months. Think it through in a hypothetical way: If they gave a new gold and elixir level at TH8, and assuming every active player had 5 free builders, and started upgrading 5 mines/pumps as soon as they could, that would mean there would instantly be 40% less loot generated across the board. Of course not everyone would put 5 builders on to these upgrades right away, but that's why I say adding a new level would take months before it could be seen as a positive influence.
Buffing existing levels would be the only choice between buffing or new levels.
