Pie-Breaking Justification

Why do you excuse Master of Waves for "being fragile" but hornet queen is "6 flying power" when it's a 2/2 and a bunch of 1/1s? Is Precursor Golem (three 3/3s and "when a spell targets only a golem copy it to each other golem") counted as "a gamble on your opponent getting free value" or "9 power for five mana?" Also, do you feel this pie-breaking infraction is more serious than an accidental combo (splinter twin) or wrong evaluation on a card's format impact (thragtusk) ? All seem serious.

Blue is allowed to make tokens. That is well within blue’s part of the color pie. It’s not a weakness. Flying is supposed to be a green weakness. Green has all sorts of answer to flying because it’s not supposed to get good fliers. Combos will happen but they are much harder to see or catch. Making a card which unto and by itself breaks the color pie, especially when it weakens color vulnerabilities, is something we should have the self-control not to do.
